The profit-maximizing price of e-books relating to do-it-yourself topics is $5.35 and the average total cost of producing e-books is $4.35.
Profit-maximizing price and average total costa. Profit-maximizing price
The maximum that the firm can earn is $35,000 at a quantity of 35,000 copies
Fixed cost FC = $140,000
Variable cost vc=$0.35 per book
Total Revenue TR =P XQ
Total Revenue TR= P x 35,000
Total Cost TC = FC + VC XQ
Total Cost TC = 140,000 + (0.35×35,000)
Total Cost TC = 140,000 +$12,250
Total Cost TC = $152,250
Profit = TR- TE
35,000 = 35,000P- $152,250
35,000P=187,250
P=187,250/35,000 copies
P=$5.35
b. Average total cost
Average total cost=Total cost/Quantity
Average total cost= $152,250/35,000 copies
Average total cost=$4.35
Therefore the profit-maximizing price of e-books relating to do-it-yourself topics is $5.35 and the average total cost of producing e-books is $4.35.

The complete question is:
A firm that sells e-books - books in digital form downloadable from the Internet - sells all e-books relating to do-it-yourself topics (home plumbing, gardening, and so on) at the same price. At present, the company can earn a maximum annual profit of $35,000 when it sells 35,000 copies within a year's time. The firm incurs a 35-cent expense each time a consumer downloads a copy, but the company must spend $140,000 per year developing new editions of the e-books. The company has determined that it would earn zero economic profits if price were equal to average total cost, and in this case it could sell 40,000 copies. Under marginal cost pricing, it could sell 120,000 copies.
In the short run, to the nearest cent, what is the profit-maximizing price of e-books relating to do-it-yourself topics?
At the profit-maximizing quantity, to the nearest cent, what is the average total cost of producing e-books?

What is the present value of a cash inflow of 1250 four years from now if the required rate of
return is 8% (Rounded to 2 decimal places)?
Using simple interest, it is found that the present value of the cash inflow is of 947.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
A(t) = A(0)(1 + rt)
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.In this problem, the parameters are given as follows:
r = 0.08, t = 4, A(t) = 1250.
We have to solve for A(0) to find the present value, hence:
A(t) = A(0)(1 + rt)
1250 = A(0)(1 + 0.08 x 4)
A(0) = 1250/1.32
A(0) = 947.

A line has slope Four-thirds. Through which two points could this line pass?
Answer:
Two points this line can pass through (1, 4/3) and (2, 8/3)
Step-by-step explanation:
The equation of the line is written in the slope-intercept form,
y = mx + b
where m represents the slope
b represents the y-intercept
where the format of a point is (x, y)
Given:
slope = 4 / 3equation: y = 4/3xwe can plug in a number for x to find y
when x = 0,
y = 4/3(0)
y = 0
point: (0,0)
when x = 1,
y = 4/3(1)
y = 4/3
point: (1, 4/3)

Find the smallest number such that
when divided by 18, the remainder
is 17, when divided by 20 the
remainder is 19 and when divided
by 24, the remainder is 23.
Answer:
I think the answer is 7
don't blame me if I'm wrong
Answer:
359
Step-by-step explanation:
the prime factors of the numbers are
18 = 2×3×3
20 = 2×2×5
24 = 2×2×2×3
the lowest common multiple is therefore
2×2×2×3×3×5 = 360
the difference between the checked divisor numbers and the expected remainder is constantly 1 :
18 - 17 = 1
20 - 19 = 1
24 - 23 = 1
so, we can deduct this constant 1 from the LCM and get the desired number :
360 - 1 = 359
verify :
359 ÷ 18 = 19 remainder 17
359 ÷ 20 = 17 remainder 19
359 ÷ 24 = 14 remainder 23

1. EL precio a la venta de una impresora de inyección de tinta es de $285.000 incluida una Ganancia del 35%. ¿cuánto le cuesta a la tienda cada impresora?
Excluyendo el componente de ganancia del coste para el consumidor según (1), la impresora tuvo un coste de $ 211.111,11 para el vendedor.
¿Cómo encontrar el precio de una impresora sin ganancia?
En el enunciado tenemos el precio de una impresora para el consumidor, el cual comprende el dinero invertido por vendedor más la ganancia esperada. Este indicador observa la siguiente fórmula:
C' = C · (1 + r/100) (1)
Donde:
C - Coste asumido por el vendedor, en unidades monetarias.C' - Coste para el consumidor, en unidades monetarias.r - Tasa de ganancia, en porcentaje.Si sabemos que C' = $ 285.000 y r = 35 %, entonces el coste asumido por el vendedor es:
285.000 = 1,35 · C'
C' ≈ 211.111,11

Separable differential equation
y’ln^2y+ysqrtx=0 y(0)=e
By applying the theory of separable ordinary differential equations we conclude that the solution of the differential equation [tex]\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0[/tex] with y(0) = e is [tex]y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}[/tex].
How to solve separable differential equation
In this question we must separate each variable on each side of the equivalence, integrate each side of the expression and find an explicit expression (y = f(x)) if possible.
[tex]\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0[/tex]
[tex](\ln y)^{2}\,dy = -y \cdot \sqrt{x}\, dx[/tex]
[tex]-\frac{(\ln y)^{2}}{y}\, dy = \sqrt{x} \,dx[/tex]
[tex]-\int {\frac{(\ln y)^{2}}{y} } \, dy = \int {\sqrt{x}} \, dx[/tex]
If u = ㏑ y and du = dy/y, then:
[tex]-\int {u^{2}\,du } = \int {x^{\frac{1}{2} }} \, dx[/tex]
[tex]-\frac{1}{3}\cdot u^{3} = \frac{2\cdot x^{\frac{3}{2} }}{3} + C[/tex]
[tex]u^{3} = -2\cdot x^{\frac{3}{2} } + C[/tex]
[tex](\ln y)^{3} = - 2\cdot x^{\frac{3}{2} } + C[/tex]
[tex]C = (\ln e)^{3}[/tex]
[tex]C = 1[/tex]
And finally we get the explicit expression:
[tex]\ln y = \sqrt [3]{-2\cdot x^{\frac{3}{2} }+ 1}[/tex]
[tex]y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}[/tex]
By applying the theory of separable ordinary differential equations we conclude that the solution of the differential equation [tex]\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0[/tex] with y(0) = e is [tex]y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}[/tex].
