To determine how much Mark would make if he works 3, 5, and 7 hours at a rate of $15.25 per hour, we can calculate his earnings for each of those hours:
-
For 3 hours:
\( 3 \text{ hours} \times 15.25 \text{ dollars/hour} = 45.75 \text{ dollars} \) -
For 5 hours:
\( 5 \text{ hours} \times 15.25 \text{ dollars/hour} = 76.25 \text{ dollars} \) -
For 7 hours:
\( 7 \text{ hours} \times 15.25 \text{ dollars/hour} = 106.75 \text{ dollars} \)
Now, we can compile these values into a sequence:
- Earnings: $45.75 (for 3 hours), $76.25 (for 5 hours), $106.75 (for 7 hours)
Thus, the correct response is:
$45.75, $76.25, $106.75
