C(n) = 2.25n + 1.25
C(n) = 2.25n + 1.25
C(n) = n
C(n) = n
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) = 3.50n
C(n) = 3.50n
C(n) = 1.25n - 2.25
C(n) = 1.25n - 2.25

Part 1) The price of each can of chicken noodle soup is $1.25. The coupon gives a discount of $2.25 off the total purchase. To calculate the total cost of purchasing n cans of chicken soup, we need to multiply the price per can by the number of cans, and then subtract the coupon discount. Therefore, the function rule for the cost C(n) of n cans of chicken soup would be:
C(n) = 1.25n - 2.25
Part 2) To find out the cost of 11 cans of chicken soup, we can substitute n = 11 into the function rule:
C(11) = 1.25(11) - 2.25
C(11) = 13.75 - 2.25
C(11) = 11.50
Therefore, 11 cans of chicken soup would cost $11.50.
