Part 1) The correct function rule for the cost of the first of n cans is: 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:
C(11) = 1.25(11) - 2.25 = 13.75 - 2.25 = $11.50
Therefore, 11 cans of chicken soup would cost $11.50.
The correct answer is: O $11.50
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.
Part 1) Write a function rule for the first of n cans.
O C(n) = 2.25n - 1.25
O C(n) = 1.25n - 2.25
O C(n) = 1.25n + 2.25
O C(n) = 2.25n + 1.25
O C(n) = 3.5n
O C(n) = n
Part 2) How much would 11 cans of chicken soup cost?
O $10.00
O $23.50
O $11.50
O $16
O $11.00
O $26
O $10.50
