Mrs Hun gave Sabrina and Pamela some money each on Thursday. On Friday, Sabrina gave ¹₄ of the amount she had to Pamela. On Saturday, Pamela gave ¹₆ of the amount she had to Sabrina. In the end, Sabrina had $30 and Pamela had $30. How much did Pamela had more than Sabrina at first?

	Sabrina	Pamela	Total
Before 1	4 u	?	$60
Change 1	- 1 u	+ 1 u
After 1	3 u	6 p	$60
Before 2	$30 - 1 p	6 p	$60
Change 2	+ 1 p	- 1 p
After 2	$30	5 p ($30)	$60

Amount that Pamela had in the end = 5 p

5 p = 30

1 p = 30 ÷ 5 = 6

Working backwards.

Amount that Sabrina had after giving to Pamela on Friday
= 30 - 1 p
= 30 - 6
= $24

3 u = 24

1 u = 24 ÷ 3 = 8

Amount that Sabrina had at first
= 4 u
= 4 x 8
= $32

Total amount that Sabrina and Pamela had 
= 30 + 30
= $60

Amount that Pamela had at first
= 60 - 32
= $28

Amount that Sabrina had more than Pamela
= 32 - 28 
= $4

Answer(s): $4
