Use reasoning to lead to the answer of the following question:
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?

5
If 6 friends each want 2 bars, that's 6 friends * 2 bars = 12 bars needed.

Each box contains 3 bars, so 12 bars / 3 bars per box = 4 boxes needed.

A box is $7, so 4 boxes * $7.

50 = $30.

There are 6 friends so $30 / 6 friends = $5 per person.

.

The answer is 5
