So this is a two step equation. The first step would be to find out how many times 20 goes into 140. 140/20=8 So if she makes 5 bracelets for every 20 dollars she makes, and she made 20 dollars 8 time. She would’ve made 5 bracelets, 8 times. So take 5 bracelets and multiply it by 8. She needs to make 40 bracelets. :)
