Question

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?

A. y = 12x + 0.75
B. y = 0.75x + 12
C. y = 12x – 0.75
D. y = 0.75x – 12

Answer 1

B. y = .75x + 12

Explanation:

The cost of one battery is $0.75. The toy itself costs $12.

The answer is y= 0.75x+12

Answer 2

i believe its B because y= the cost of batteries (0.75) times the number of batteries (x) + how much the toy costs (12) so y=0.75x+12
