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?
Hint:
Don't forget your leftovers.

15$ = 15 apples + 15 wrappers
= 15 apples + (5 apples + 5 wrappers)
= 15 apples + 5 apples + (3 apples + 3 wrappers) + 2 wrappers
= 15 + 5 + 3 ( 1 apple + (1 wrapper + 2 warrper) )
= ( 15 + 5 + 3 + 1 apple) + 3 wrapper
= 24 apple + 3wrapper
= 24 apple + 1 apple and 1 wrapper
= 25 apple and 1 wrapper.
tama?

20 apples?
I agree with 20 apple.
heres the computation:
1 apple=$1
3wrapper=1 apple
$15=(1apple/$1)
apple=15
since you have 15 apple it means you have 15 wrappers.
so,
15wrappers/3wrappers =5
15+5=20
20 apples is wrong
