B. 1 out of 4
C. 4 out of 6
D. 5 out of 10
E. 1 out of 10
Answer:
y = 12 + 0.75 x
Step-by-step explanation:
Here, x represents the number of batteries used for a toy and y represents total estimated total cost,
Since, the cost of a toy = $ 12,
And, the cost of one battery = $ 0.75,
⇒ The cost of x batteries = 0.75 x dollars,
Since, total cost = the cost of the toy + the cost of x batteries
⇒ y = 12 + 0.75 x
Which is the required equation that represents the given situation.
