Mrs Lu gave Marion and Esther some money each on Tuesday. On Wednesday, Marion gave ¹₆ of the amount she had to Esther. On Thursday, Esther gave ¹₃ of the amount she had to Marion. In the end, Marion had $62 and Esther had $4. How much did Esther had more than Marion at first?

	Marion	Esther	Total
Before 1	6 u	?	$66
Change 1	- 1 u	+ 1 u
After 1	5 u	3 p	$66
Before 2	$62 - 1 p	3 p	$66
Change 2	+ 1 p	- 1 p
After 2	$62	2 p ($4)	$66

Amount that Esther had in the end = 2 p

2 p = 4

1 p = 4 ÷ 2 = 2

Working backwards.

Amount that Marion had after giving to Esther on Wednesday
= 62 - 1 p
= 62 - 2
= $60

5 u = 60

1 u = 60 ÷ 5 = 12

Amount that Marion had at first
= 6 u
= 6 x 12
= $72

Total amount that Marion and Esther had 
= 62 + 4
= $66

Amount that Esther had at first
= 66 - 72
= $-6

Amount that Marion had more than Esther
= 72 - -6 
= $78

Answer(s): $78
