Answers:

Nora = $40

Sara = $55

=========================================================

Work Shown:

n = amount Nora earned

s = amount Sara earned

n+s = 95 .... total amount earned

s = n+15 .... since Sara earned $15 more than Nora

--------------

I'll use the substitution method to solve.

n+s = 95

n+n+15 = 95 ....... replaced "s" with n+15

2n+15 = 95

2n = 95-15

2n = 80

n = 80/2

n = 40 dollars is the amount Nora earned

s = n+15

s = 40+15

s = 55 dollars is the amount Sara earned

--------------

Check:

Nora+Sara = 40+55 = 95 dollars total earned

This confirms the answer. Also, we can see that Sara earned $15 more than Nora to help further confirm the answer.
