The square footage of the two bedrooms in the apartment that Jenny and Martha share totals 300 square feet. If Jenny's bedroom is 60 square feet larger than Martha's, how large, in square feet, is Martha's bedroom?
Let M be the number of square feet in Matha's bedroom
Jenny's bedroom is M+60 square feet.
M+M+60=300
2M+60=300
2M=240
M=<<120=120>>120
Martha's bedroom is 120 square feet.
