To find out how much John will earn this week, we need to evaluate the expression \(15j + 12t\) by substituting \(j = 8\) and \(t = 6\).
1. Substitute the values into the expression:
\[
15(8) + 12(6)
\]
2. Calculate \(15(8)\):
\[
15 \times 8 = 120
\]
3. Calculate \(12(6)\):
\[
12 \times 6 = 72
\]
4. Now add the two results together:
\[
120 + 72 = 192
\]
Thus, John will earn **$192** this week.
