Joni sells kitchen aprons online for $32.50 each. How many aprons must she sell next month if she wants to earn at least $1,000?
Answer:
she must sell 31 aprons
The number of aprons Joni must she sell next month if she wants to earn at least $1,000 is 31.
In order to determine the number of aprons that Joni should sell in order to make at least $1000 next month, we would dived the total amount Joni hopes to make by the unit cost of an apron.
Number of aprons to sell = Amount Joni hopes to earn / unit cost of an apron.
$1000 / $32.50 = 30.77
Rounding off to the nearest whole number, the number of aprons that Joni should sell is 31.

Two
pages
that face each other in a book have 343 as the sum of their page
numbers. What is the number of the page that comes first?
Answer:
171
Step-by-step explanation:
I divided 340 first and got 170 for each page number then I had 3 left over.
I added 1 to 170 and got 171 the I added the left over 2 to the other 170 and got 172.
So the first page number should be 171 :)
I hope this helped you understand :)
The number of page that comes first is 171.
It is given that in a book two pages that face each other have sum of 343 of their page numbers.
We have to find out what will be the number of page that comes first.
What will be the value of x , if x + (x + 2 ) = 18 ?
The value of x will be equal to ; 2x + 2 = 18 or 2x = 16 or x = 16 ÷ 2 or x = 8.
As per the question ,
In a book sum of two pages that face each other = 343
Let's assume that the page which comes first will be have page number x.
So,
x + (x + 1) = 343
2x + 1 = 343
2x = 342
x = 342 ÷ 2
x = 171
The other page will have number :
= x + 1
= 171 + 1
= 172
Thus , the number of page that comes first is 171.

Answer: angle ITU = 145 degrees
===============================================
Explanation:
Angle STU is the largest angle composed of the smaller angles STI and ITU.
In other words, the two smaller angles add up to the larger one.
(angle STI) + (angle ITU) = angle STU
( 20 ) + ( 12x+1 ) = 13x + 9
20+12x+1 = 13x+9
12x+21 = 13x+9
21-9 = 13x-12x
12 = x
x = 12
Using this x value, we find that,
angle ITU = 12x+1 = 12(12)+1 = 145 degrees
----------
As a side note,
angle STU = 13x+9 = 13(12)+9 = 165 degrees
This is confirmed with
(angle STI) + (angle ITU) = (20) + (145) = 165 = angle STU

A waitress sold ribeye steak dinners and grilled salmon dinners, totaling $ on a particular day. Another day she sold ribeye steak dinners and grilled salmon dinners, totaling $. How much did each type of dinner cost?
Answer:
ribeye steak: $24.37grilled salmon: $9.30Step-by-step explanation:
If we let r and g represent the costs of a ribeye steak dinner and grilled salmon dinner, respectively, the sales figures give rise to two equations.
17r +15g = 553.74
22r +5g = 582.65
If we multiply the second equation by 3 and subtract the first, we have ...
3(22r +5g) -(17r +15g) = 3(582.65) -(553.74)
49r = 1194.21
r = 1194.21/49 ≈ 24.37
g = (553.74 -17r)/15 ≈ 9.30
The steak dinner costs $24.37; the salmon dinner costs $9.30.
_____
Check
17(24.37) +15(9.30) = 553.79 . . . not 553.74
22(24.37) +5(9.30) = 582.64 . . . not 582.65
There is no exact solution to this problem.
Answer:
R=cost of rib-eye dinner; S=cost of salmon dinner

The octane rating of gasoline is the percentage of isooctane in the fuel. For example, 89-octane gasoline contains 89% of isooctane. How many liters of 88-octane gasoline should be mixed with 100 liters of 95-octane gasoline to get a mixture which is 93-octane gasoline ?
Answer:
40 liters of 88-octane gasoline should be mixed
Step-by-step explanation:
Here in this question, we are interested in calculating the number of liters of 88-octane gasoline that should be mixed with 100 liters of 95-octane gasoline to get a mixture of 93-octane gasoline.
Since we do not know the number of liters, we can represent it by x
This means that the total number of liters of the 93-octane gasoline we are looking at producing is (100 + x) liters.
Thus, if we multiply the number of liters of each gasoline type by their isooctane content and add together, we will obtain the product;
Hence;
88(x) + 100(95) = 93(100 + x)
88x + 9500 = 9300 + 93x
93x -88x = 9500-9300
5x = 200
x = 200/50
x = 40 liters
