4 u |

$240 |
The total amount that Ian and Andy had remains unchanged.
Total amount in the end
= 4 u + 1 u
= 5 u
5 u = 240
1 u = 240 ÷ 5 = 48
Amount that Andy has in the end
= 4 u
= 4 x 48
= $192
Amount that Ian has in the end
= 1 u
= $48
4 p = 1 u = 48
1 p = 48 ÷ 4 = 12
Amount that Ian gave to Andy
= 1 p
= 1 x 12
= $12
Amount that Andy had at first
= 192 - 12 + 47
= $227
Answer(s): $227
