A box of ice cream bars costs $7.50 and contains three bars.  6 friends want to each eat 2 bars.  How much money will that require per person?
If 6 friends each want 2 bars, that's 6 friends * 2 bars = <T>multiply(6, 2)=12 bars needed.
Each box contains 3 bars, so 12 bars / 3 bars per box = <T>divide(12, 3)=4.0 boxes needed.
A box is $7, so 4 boxes * $7.50 = $<T>multiply(4, 7.5)=30.0
There are 6 friends so $30 / 6 friends = $<T>divide(30, 6)=5.0 per person.
