I'm sorry, but without any context or specific question, it is not possible to determine whether $7.00 or $7.50 is the answer. Can you please provide more information or clarify your question?
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?

C(n) = 0.5n – 0.75; $4.25
C ( n ) = 0.5 n – 0.75; $4.25
C(n) = 0.75n – 0.5; $7.00
C ( n ) = 0.75 n – 0.5; $7.00
C(n) = 0.5n – 0.5; $4.50
C ( n ) = 0.5 n – 0.5; $4.50
C(n) = 0.75n; $7.50

The correct option is C(n) = 0.75n - 0.5; $4.50.
To find the cost of n sodas, we multiply the price per can ($0.75) by the number of sodas (n) and then subtract the coupon amount ($0.50), resulting in the function rule C(n) = 0.75n - 0.50.
To calculate the cost of 10 sodas, we substitute n = 10 into the function: C(10) = 0.75(10) - 0.50 = $7.50 - $0.50 = $7.00. Therefore, 10 sodas would cost $7.00.
