Question

4. A construction company pays carpenters $15 an hour for the first 40 hours they work in a week, and $20 for each additional hour they work. Which expression could be used to find a carpenter's salary if he worked h hours over 40? A (15 X 40) + (20 H) B. (20 x 40) + (15 x h) c. (15 X 40) X (20 x h) D. (15 x 40) X (20 + h) Х

Answer 1

The correct answer is A (15 X 40) + (20H)

Answer 2

Let h be the number of additional hours. Since the fixed pay is 15 dollars for the first 40 hours, this means that from there, each hour will be paid with 20 dollars. We can write the following equation to represent this situation:

`y=40\cdot15+20h`
