Mrs Thia gave Gabby and Jaslyn some money each on Tuesday. On Wednesday, Gabby gave
15 of the amount she had to Jaslyn. On Thursday, Jaslyn gave
14 of the amount she had to Gabby. In the end, Gabby had $50 and Jaslyn had $6. How much did Jaslyn had more than Gabby at first?

$56 |
Amount that Jaslyn had in the end = 3 p
3 p = 6
1 p = 6 ÷ 3 = 2
Working backwards.
Amount that Gabby had after giving to Jaslyn on Wednesday
= 50 - 1 p
= 50 - 2
= $48
4 u = 48
1 u = 48 ÷ 4 = 12
Amount that Gabby had at first
= 5 u
= 5 x 12
= $60
Total amount that Gabby and Jaslyn had
= 50 + 6
= $56
Amount that Jaslyn had at first
= 56 - 60
= $-4
Amount that Gabby had more than Jaslyn
= 60 - -4
= $64
Answer(s): $64
