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

Step-by-step explanation:

: total cost

: number of batteries

If the toy costs $12, the total cost must be those $12 plus the amount of money spent in the batteries.

Money spent in batteries:

this is because each battery costs $0.75, is he uses amount of batteries he must pay the

Thus, the total cost is

which is the cost of the batteries and the cost of the toy added together.
