Mrs Leng gave Jade and Roshel some money each on Tuesday. On Wednesday, Jade gave
16 of the amount she had to Roshel. On Thursday, Roshel gave
15 of the amount she had to Jade. In the end, Jade had $67 and Roshel had $48. How much did Roshel had more than Jade at first?

$115 |
Amount that Roshel had in the end = 4 p
4 p = 48
1 p = 48 ÷ 4 = 12
Working backwards.
Amount that Jade had after giving to Roshel on Wednesday
= 67 - 1 p
= 67 - 12
= $55
5 u = 55
1 u = 55 ÷ 5 = 11
Amount that Jade had at first
= 6 u
= 6 x 11
= $66
Total amount that Jade and Roshel had
= 67 + 48
= $115
Amount that Roshel had at first
= 115 - 66
= $49
Amount that Jade had more than Roshel
= 66 - 49
= $17
Answer(s): $17
