To evaluate the expression \(15l + 12s\) for \(l = 5\) and \(s = 7\), we substitute the values of \(l\) and \(s\) into the expression.
1. Substitute \(l = 5\) and \(s = 7\) into the expression:
\[
15(5) + 12(7)
\]
2. Calculate \(15(5)\):
\[
15 \times 5 = 75
\]
3. Calculate \(12(7)\):
\[
12 \times 7 = 84
\]
4. Now, add the two results together:
\[
75 + 84 = 159
\]
Therefore, Jacqueline will earn **$159** at her two jobs this week.
