To find out how much Jamal will earn over 7 years if he continues at the same rate of pay, we can use the equation that multiplies his annual salary by the number of years.
The correct equation for Jamal's total earnings over 7 years is:
C. \( y = 125,000 \times 7 \)
This equation represents that his total earnings (y) will be his annual salary ($125,000) multiplied by the number of years (7).
