The cost of a repair which depends on the hoursof labor it takes to make the repair is $200 which of the following best shows this in function notation?

A cost (hours) = $200

B cost ($200) = hours

C Hours ($200) = cost

D Hours (cost) = $200

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.

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