Jacqueline has two part time jobs. She earns $15 per hour, l, as a lab assistant and $12 per hour,s, as a cashier. This is modeled by 15l+12s. Evaulate for l=5 and s=7 to find out how much money Jacqueline will earn at her two jobs this week.

1 answer

To find out how much money Jacqueline will earn this week from her two jobs, we can evaluate the expression \( 15l + 12s \) using the values \( l = 5 \) (hours worked as a lab assistant) and \( s = 7 \) (hours worked as a cashier).

Now, substitute the values into the expression:

\[ 15l + 12s = 15(5) + 12(7) \]

Calculating each term:

  1. \( 15(5) = 75 \)
  2. \( 12(7) = 84 \)

Now, add these two results together:

\[ 75 + 84 = 159 \]

Thus, Jacqueline will earn $159 this week from her two jobs.
