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**.
