Tony paid $7 for 2 dozen apples and 1 bunch of bananas. Arnold paid $5 for 1 dozen apples and 1 bunch of bananas. How much does a bunch of bananas cost?
assistant
How much did Tony pay? ** Tony paid $7-$5= $<<7-5=2>>2 more than Arnold
How many apples did Tony buy? ** We know he bought the same number of bananas as Arnold but that he bought 2-1=1 dozen apples more than Arnold
How much do a dozen apples cost? ** Therefore a dozen apples should cost $2
How much does a bunch of bananas cost? ** If Arnold paid $5 and $2 for a dozen apples then the bunch of bananas cost $5-$2=$<<5-2=3>>3
