Suppose noodle soup is on sale for $0.75 a can, and you have a coupon for $0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point) Responses C(n) = 0.75n – 0.5 C ( n ) = 0.75 n – 0.5 C(n) = 0.5n – 0.75 C ( n ) = 0.5 n – 0.75 C(n) = (0.75 + n) – 0.5 C ( n ) = (0.75 + n) – 0.5 C(n) = (0.5 + n) – 0.75

The correct function rule for the cost of n cans of soup is C(n) = 0.75n - 0.5.
