To find how much money Jacqueline will earn this week, we need to substitute l = 5 and s = 7 into the expression 15l + 12s.
15(5) + 12(7) = 75 + 84 = 159.
Therefore, Jacqueline will earn $159 at her two jobs this week.
Jacqueline has two part-time jobs. She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier. This is modeled by 15l + 12s. Evaluate for
1 = 5 and s = 7 to find how much money Jacqueline will earn at her two jobs this week.
