Start by turning the words into equations. "A woman earns 15% more than her husband." What does that mean in numbers? It means she makes 115% of what he does.
W=1.15%2AH
Part 2 of the problem. "Together they make $69,875." Stated another way, when you add his and her salary together, it equals 69,875. How can you turn that into an equation?
W%2BH=69875
Then you need to solve for either the wife's or husband's salary, and use that answer to figure out what the other made. We do this by substituting 1 equation into the other. Since we already know what W equals, let's plug it in and see what happens:
W%2BH=69875
1.15H%2BH=69875
2.15H=69875
H=32500
So we know he makes $32,500 per year. 1 down, 1 to go. Now just pick a formula and subsitute in $32,500 for H. It doesn't matter which one you pick, you'll get the same answer.
W%2BH=69875
W%2B32500=69875
W=69875-32500=37375
or using the other one
W=1.15%2AH
W=1.15%2A32500=37375
Either way, you now have the two salaries. He makes $32,500 and she makes $37,375.
