Question

Erica earned a total of 67,160 last year from her two jobs. The amount she earned from her job at the store was 1,550 more than three times the amount she earned from her job at the college. How much did she earn (in dollars) from her job at the college

Answer 1

Let's call the amount Erica earned from her job at the college "x". We know that:

Total income = $67,160

Income from store = 3x + 1,550

Total income = Income from store + Income from college

67,160 = 3x + 1,550 + x

67,160 = 4x + 1,550

Now we can solve for x:

67,160 - 1,550 = 4x

65,610 = 4x

x = 16,402.5

Erica earned $16,402.50 from her job at the college.
