A class is organizing a going away party for one of their students. They spend $26.38 on decorations, $78.92 on food, and $34.50

Serjik [45]

Answer:

$9.35

Step-by-step explanation:

Simply start by adding up the total cost of each item.

$26.38 + $78.92 + $34.50

= $140.25

The total is $140.25

If 15 students want to split the cost, you’ll need to divide it by 15.

$140.25 divided by 15 = $9.35

So the total for each student is $9.35

n your computer store you charge $1012 per computer sold. Your costs are given by the equation C(x) = 4x^2 + 4x - 80 where x is

ella [17]

Answer:

63568 dollars

Step-by-step explanation:

Given that in your computer store you charge $1012 per computer sold. Your costs are given by the equation

$C(x) = 4x^2 + 4x - 80$

where x is the number of computers sold.

Revenue = sales price *no of computers sold

= 1012x

Profit = Revenue - cost

= $1012x-( 4x^2 + 4x - 80)\\= 1008x-4x^2+80\\$

Use derivative test to find maximum profit

$C'(x) = 1008-8x \\C''(x)= -x$

Equate I derivative to 0

x= 128

i.e. if 128 computers are manufactured and sold profit wouldbemaximum

Profit maximum= $1008(128)-4(128)^2+80\\=63568$
