I need some help with this problem.
Jennifer is a college student who works two jobs after school and on weekends trying to make extra spending money and to help pay her tuition. At Job A, she gets $8 an hour, and at Job B, she gets 10 an hour.
1. If Jennifer only works at Job A, write an equation for her total income l for working a hours.
2. How much will she make if works 20 hours in the week? Justify your answer.
