Suppose tuna is on sale for $0.90 a can, and you have a coupon for $0.40 off your total purchase. Write a function rule for the cost of the n cans of tuna. (1 point)

Responses

C(n)=0.90n−0.40
cap c times n is equal to 0 point 9 0 n minus 0 point 4 0

C(n)=0.40n−0.90
cap c times n is equal to 0 point 4 0 n minus 0 point 9 0

C(n)=(0.90+n)−0.40
cap c times n is equal to open paren 0 point 9 0 plus n close paren minus 0 point 4 0

C(n)=(0.40+n)−0.90
