Soda 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 sodas. How much would 10 sodas cost? (1 point) Responses C(n) = 0.5n – 0.75; $4.25 C(n) = 0.75n – 0.5; $7.00 C(n) = 0.5n – 0.5; $4.50 C(n) = 0.75n; $7.50
C(n) = 0.75n - 0.50; $7.00
The cost of 10 sodas would be C(10) = 0.75(10) - 0.50 = $7.00.
