Mrs Chong gave Nora and Linda some money each on Tuesday. On Wednesday, Nora gave
16 of the amount she had to Linda. On Thursday, Linda gave
14 of the amount she had to Nora. In the end, Nora had $43 and Linda had $9. How much did Linda had more than Nora at first?

3 p

$52 |
Amount that Linda had in the end = 3 p
3 p = 9
1 p = 9 ÷ 3 = 3
Working backwards.
Amount that Nora had after giving to Linda on Wednesday
= 43 - 1 p
= 43 - 3
= $40
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that Nora had at first
= 6 u
= 6 x 8
= $48
Total amount that Nora and Linda had
= 43 + 9
= $52
Amount that Linda had at first
= 52 - 48
= $4
Amount that Nora had more than Linda
= 48 - 4
= $44
Answer(s): $44
