To find out how much Bailey will earn at his two jobs this week, we can evaluate the expression \(13c + 18t\) using the given values for \(c\) and \(t\).
We have:
- \(c = 10\) (hours worked as a cashier)
- \(t = 12\) (hours worked as a technology support specialist)
Now, substituting these values into the expression:
\[ 13c + 18t = 13(10) + 18(12) \]
Calculating each term:
\[ = 130 + 216 \] \[ = 346 \]
Therefore, Bailey will earn $346 at his two jobs this week.
The correct response is $346.
