Answer:
$720
Step-by-step explanation:
Given the following functions
Cost function C(x)=50x+400
Revenue function R(x)=80x-0.05x^2
P(x)=R(x)−C(x).
Profit function P(x) = 80x-0.05x^2 - (50x+400)
P(x) = 80x-0.05x^2 - 50x - 400
Substitute x = 40
P(40) = 80(40)-0.05(40)^2 - 50(40) - 400
P(40) = 3200-80-2000-400
P(40) =3200-2480
P(40) = 720
Hence the amount of profit made is $720

$12.50 pre-tax, the tax was 9%, and you tipped
10% on the pre-tax amount?
Answer:
12.50/100 X 110 = 13.75
13.75-12.50 = 1.25
12.50/100 X 109 = 13.625
13.625 + 1.25 = 14.875

In a basketball game, Alison made 6 of 13 free shots.
Madhu made 5 of 9 free shots. Who played better? Explain.
Answer:
Madhu played better.
Step-by-step explanation:
Change both fractions to where they have the same denominator to see which one is bigger. The smallest possible denominator between the two fractions is 117.
To get the 13 in 6/13 to become 117, you had to multiply it by 9. Whatever you do to the denominator, you must do to the numerator.
6 x 9 = 54.
Allison's fraction is now 54/117.
To get the 9 in 5/9 to become 117, you had to multiply the 9 by 13. Whatever you do to the denominator, you must do to the numerator.
5 x 13 = 65
Madhu's fraction is now 65/117
By looking, 65 is larger than 54, so Madhu had a larger number of shots compared to shots not made than Allison.

Patty counted 250 chocolate chips on a tray of cookies. The actual amount of chocolate chips on the tray were 265. What is the percent error? *
Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100
percent error= 265-250/250*100
percent error=15/250*100
percent error=0.06*100
percent error=6%
Question in the picture. Thanks
Answer:

Which problem can be solved using 3 x 7= 21?
Answer:
2nd one
Step-by-step explanation:
phil has 3 tables with 21 balloons on each
D would be the answer to solve 3x7=21. A is adding 21 with 3 and B is multiplying 3 and 21 witch isn’t what we’re looking for. Then for C, it would be subtracting 22 by 3. D is the only one witch said that Phil has 21 balloons and he put the same number of ballon on 3 tables. This way they can divide 21 with 3 and gives the quotient of 7. So D would be the best answer t solve he problem 3x7=21.
