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)
O C(n) = 0.5n – 0.75; $4.25 OC(n) = 0.75n-0.5; $7.00
OC(n) = 0.5n-0.5, $4.50
O C(n) = 0.75n; $7.50
The correct function rule for the cost of n sodas is:
C(n) = 0.75n - 0.50
To find out how much 10 sodas would cost, plug in n = 10 into the function:
C(10) = 0.75(10) - 0.50
C(10) = 7.50 - 0.50
C(10) = 7.00
Therefore, 10 sodas would cost $7.00.
