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. (1 point)
$______
$15*5 + $12*7 = $75 + $84 = $159
To find how much money Jacqueline will earn at her two jobs this week, we substitute l = 5 and s = 7 into the expression 15l + 12s and evaluate.
So, we have:
15(5) + 12(7)
Evaluating this expression step by step, we get:
75 + 84
Adding the two numbers together, we find:
159
Therefore, Jacqueline will earn $159 at her two jobs this week.
