Question

Your job pays $6 per hour. Write a variable expression for your pay in dollars for working h hours. What is your pay if you work 30 hours? (A) 6; $174 (B) 6h; $180 (C) 6h; $186 (D) 7h; $180

Answer 1

The answer is B. 6h shows you earn $6 per hour, and 30 hours x $6 is $180.

Answer 2

(B) 6h; $180

Explanation:

Let h represents the number of hour.

Given,

Payment for an hour = $ 6,

So, the payment for h hours = 6h dollars,

Where, h is a variable.

Thus, the required variable representation is 6h.

If h = 30,

Thus, the total payment for 30 hours

= 6 ( 30 )

= $ 180

Hence, option B is correct.
