Mrs Chew gave Kylie and Raeann some money each on Thursday. On Friday, Kylie gave
14 of the amount she had to Raeann. On Saturday, Raeann gave
16 of the amount she had to Kylie. In the end, Kylie had $26 and Raeann had $10. How much did Raeann had more than Kylie at first?

$36 |
Amount that Raeann had in the end = 5 p
5 p = 10
1 p = 10 ÷ 5 = 2
Working backwards.
Amount that Kylie had after giving to Raeann on Friday
= 26 - 1 p
= 26 - 2
= $24
3 u = 24
1 u = 24 ÷ 3 = 8
Amount that Kylie had at first
= 4 u
= 4 x 8
= $32
Total amount that Kylie and Raeann had
= 26 + 10
= $36
Amount that Raeann had at first
= 36 - 32
= $4
Amount that Kylie had more than Raeann
= 32 - 4
= $28
Answer(s): $28
