To find out how much money Jacqueline will earn at her two jobs this week, we need to evaluate the expression 15l + 12s with l = 5 and s = 7.
Substituting l = 5 and s = 7, we get:
15(5) + 12(7)
This simplifies to:
75 + 84
Adding the numbers together, we get:
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 l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week.
