A shop sells apples at $1 each. Each of these apples are wrapped in a special wrapper. You can trade 3 of these wrappers for 1 apple. If you have $15, how many apples can you get altogether?

24 apples

22 apples

32 apples

This doesn't make sense because the answer is not any of these choices.

If they cost $1.00 each and you have $15.00 that buys you 15 apples

3 wrappers will get you another apple

you will get 15 wrappers. 15 wrappers

3wrappersx5apples=15wrappers total

So you get 5 apples plus the 15 apples=20 apples total
