Answer:
- 57 = (7/8)x -13
- $80
Step-by-step explanation:
1. I find it convenient to use variable names that remind me what they stand for. Here, we can use "j" to represent Joanne's earnings, and "e" to represent Erin's earnings.
j = 57 . . . . . Joanne earned $57
j = (7/8)e -13 . . . . . Joanne's earnings were $13 less than 7/8 of Erin's
Substituting for j, we get one equation for Erin's earnings
57 = (7/8)e -13
Using 'x' for Erin's earnings, this is ...
57 = (7/8)x -13

2. We can solve the equation as follows:
70 = 7/8x . . . . . . add 13
80 = x . . . . . . . . . multiply by 8/7
