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

Answer 1

To find out how much money Jacqueline will earn from her two part-time jobs this week, we can plug the values of \( l \) (lab assistant hours) and \( s \) (cashier hours) into the model \( 15l + 12s \).

Given:

• \( l = 5 \) (hours worked as a lab assistant)
• \( s = 7 \) (hours worked as a cashier)

Now, substituting these values into the equation:

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

Calculating each part:

\[ = 15 \times 5 + 12 \times 7 \]

\[ = 75 + 84 \]

Now add them together:

\[ = 159 \]

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