Noah and James are each paid $15 per hour. However, this week Noah received a $60 bonus. Given that N and J represent the number of hours worked by Noah (N) and James (J), which expression can be used to represent their combined earnings for the week?

15N+15J+60

Step-by-step explanation:

We know that Noah and James each receive $15 per hour. That means that to get the money one of them earned in a week, we multiply the money they earn ($15) by the hours they worked (N or J):

15 × N is what Noah earned.

15 × J is what James earned.

Combining those are just 15N + 15J. Then, we add the bonus Noah received ($60) to get their total combined earnings:

15N+15J+60
