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?

y = 12x + 0.75
y = 0.75x + 12
y = 12x – 0.75
y = 0.75x – 12

Answer 1

y=0.75x +12

Explanation:

Answer 2

y= 0.75x+12

Explanation:

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

The answer is y= 0.75x+12
