Sarah and Bryan went shopping and spent a total of $47.50. Bryan spent $15.50 less than what Sarah spent. How much did Bryan spend?

S+B=47.5 S-15.50=B so subtitute S-15.5 into the first equation and get
S+(S-15.5)=47.5 or
2S-15.5=47.5 add 15.5 to both sides and get 2S=64 divide both sides by 2 and get Sarah spent 32 dollars Bryan spend 32-15.5=16.5
