Question

, 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.

Answer 1

To calculate how much money Jacqueline will earn at her two jobs this week, we use the expression:

\[ 15l + 12s \]

Given that \( l = 5 \) (hours worked as a lab assistant) and \( s = 7 \) (hours worked as a cashier), we can substitute these values into the expression.

Calculating the earnings:

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

First, calculate \( 15(5) \):

\[ 15(5) = 75 \]

Next, calculate \( 12(7) \):

\[ 12(7) = 84 \]

Now, add the two results together:

\[ 75 + 84 = 159 \]

Therefore, Jacqueline will earn $159 at her two jobs this week.
