Which equation represents the situationThe 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-0.75
C: y=12x-0.75
D: y=0.75x-12

Answer 1

The equation that represents the give situation is, y = 0.75 x + 12

Explanation:

Answer 2

Answer: The equation that represents the give situation is, y = 0.75 x + 12

Explanation:

Here, x represents the number of batteries the child bought and y represents the total cost.

Since, the cost of one batteries = $ 0.75

⇒ The cost of x batteries = 0.75 x

The cost of one toy = $ 12

Hence, the total cost = The cost of one toy + The cost of x batteries

= y = 0.75 x + 12

Which is the required equation that represents the given situation.
