A company distributes college logo sweatshirts and sells them for $50 each. The total cost function is linear, and the total cost for 100 sweatshirts is $4796, whereas the total cost for 240 sweatshirts is $7036.
(a) Write the equation for the revenue function R(x).
R(x) =

(b) Write the equation for the total cost function C(x).
C(x) =

(c) Find the break-even quantity.
x =
sweatshirts

so, converting firstly the mixed fractions to improper fractions and then "adding".

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
