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?
Noah earned $15 per hour for N hours worked, so his earnings for the week are 15N + $60 (bonus).
James earned $15 per hour for J hours worked, so his earnings for the week are 15J.
Therefore, their combined earnings for the week can be represented by the expression 15N + 15J + $60.
