Moe earns 15% more than her husband Joe. Together they make 78000 per year. What is Joe’s annual salary?

Answer to two significant figures.

My answer was \$31000, but the program doesn't seem to want to take it. Did I do something wrong?

1. if Joe makes J dollars, then Moe earns 1.15J

J + 1.15J = 78000
J = 36279

So, Joe makes \$36279
Moe makes \$41721

add 'em up to get 78000
