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