Mrs Loh gave Abi and Winnie some money each on Monday. On Tuesday, Abi gave
16 of the amount she had to Winnie. On Wednesday, Winnie gave
13 of the amount she had to Abi. In the end, Abi had $62 and Winnie had $14. How much did Winnie had more than Abi at first?

$76 |

2 p

$76 |
Amount that Winnie had in the end = 2 p
2 p = 14
1 p = 14 ÷ 2 = 7
Working backwards.
Amount that Abi had after giving to Winnie on Tuesday
= 62 - 1 p
= 62 - 7
= $55
5 u = 55
1 u = 55 ÷ 5 = 11
Amount that Abi had at first
= 6 u
= 6 x 11
= $66
Total amount that Abi and Winnie had
= 62 + 14
= $76
Amount that Winnie had at first
= 76 - 66
= $10
Amount that Abi had more than Winnie
= 66 - 10
= $56
Answer(s): $56
