A can of chicken noodle soup is on sale for $1.25 a can. You have a coupon for $2.25 off your total purchase.

Question

Part 1) Write a function rule for the first of n cans.

C(n) = n
C(n) = n

C(n) = 3.50n
C(n) = 3.50n

C(n) = 1.25n + 2.25
C(n) = 1.25n + 2.25

C(n) = 2.25n - 1.25
C(n) = 2.25n - 1.25

C(n) = 1.25n - 2.25
C(n) = 1.25n - 2.25

C(n) = 2.25n + 1.25

Part 2) How much would 11 cans of chicken soup cost?

Answer 1

To find out how much 11 cans of chicken soup would cost, we can use the function rule C(n) = 1.25n + 2.25.

Substituting n = 11 into the function:

C(11) = 1.25(11) + 2.25
C(11) = 13.75 + 2.25
C(11) = 16

So, 11 cans of chicken noodle soup would cost $16.
