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?
Tony paid $7-$5= $<<7-5=2>>2 more than Arnold
We know he bought the same number of bananas as Arnold but that he bought 2-1=1 dozen apples more than Arnold
Therefore a dozen apples should cost $2
If Arnold paid $5 and $2 for a dozen apples then the bunch of bananas cost $5-$2=$<<5-2=3>>3
