Jamal earns $125,000 a year as a systems analyst. He wants to know how much he will earn if he continues at the same rate of pay for 7 years. Which equation will help him find this amount.

y = 125,000 × 7

125,000 = 7x

125,000 = 7/x

x= 125,000/7

y = 125,000 × 7

The equation that will help Jamal find his total earnings after 7 years is y = 125,000 × 7.

To find out how much Jamal will earn if he continues at the same rate of pay for 7 years, we need to use the equation:

Total earnings = Annual salary × Number of years

In this case, Jamal's annual salary is $125,000 and he wants to know how much he will earn in 7 years. So, the equation is:

Total earnings = $125,000 × 7

Simplifying this equation, we get:

Total earnings = $875,000

Therefore, Jamal will earn $875,000 if he continues at the same rate of pay for 7 years.
