Comparing Glen

4 u |

$240 |
The total amount that Eric and Glen had remains unchanged.
Total amount in the end
= 4 u + 1 u
= 5 u
5 u = 240
1 u = 240 ÷ 5 = 48
Amount that Glen has in the end
= 4 u
= 4 x 48
= $192
Amount that Eric has in the end
= 1 u
= $48
6 p = 1 u = 48
1 p = 48 ÷ 6 = 8
Amount that Eric gave to Glen
= 1 p
= 1 x 8
= $8
Amount that Glen had at first
= 192 - 8 + 27
= $211
Answer(s): $211
