A company sells boxes of cow bells (b) for $20 and boxes of air horns (h) for $30. They can make a batch of cow bells that fills 8 boxes or a batch of air horns that fills 9 boxes. The company only has 53 boxes. Which system of equations helps the company plan to make $275?

 b = 53 − h
8b + 9h = 53

 8b = 53 − 9h
20b + 30h = 275

 b = 53 − h
20b + 30h = 275

 8b = 53 − 9h
20b − 30h = 275

There really wasn't a way to explain the first question without giving the answer. @GloriaSCastillo, you should familiarize yourself more with solving systems of equations.
