To find out how much money Jacqueline earns this week, we need to evaluate the expression \( 15l + 12s \) given that \( l = 5 \) (hours as a lab assistant) and \( s = 7 \) (hours as a cashier).
Substituting the values into the expression:
\[
15l + 12s = 15(5) + 12(7)
\]
Calculating each term:
\[
15(5) = 75
\]
\[
12(7) = 84
\]
Adding these amounts together:
\[
75 + 84 = 159
\]
Thus, Jacqueline will earn **$159** this week from her two jobs.
