A cost(hours)=$200
B cost($200)=hours
C Hours($200)=cost
D Hours(cost)=$200

Respuesta :

D. Hours(cost)=$200 because think about the hours and how long it will take to get it done

Answer:

A cost(hours)=$200

Step-by-step explanation:

Let h represents the number of hours after which the cost of a repair is $ 200,

Since, according to the question,

Cost ∝ h

We can write the cost of a repair after h hours is Cost(h)

⇒ Cost(h) = $ 200

⇒ Cost (hours) = $ 200

Which is the required function notation for the given situation.

Option 'A' is correct.
