Mrs Toh gave Tammy and Natalie some money each on Thursday. On Friday, Tammy gave ¹₃ of the amount she had to Natalie. On Saturday, Natalie gave ¹₄ of the amount she had to Tammy. In the end, Tammy had $26 and Natalie had $6. How much did Natalie had more than Tammy at first?

	Tammy	Natalie	Total
Before 1	3 u	?	$32
Change 1	- 1 u	+ 1 u
After 1	2 u	4 p	$32
Before 2	$26 - 1 p	4 p	$32
Change 2	+ 1 p	- 1 p
After 2	$26	3 p ($6)	$32

Amount that Natalie had in the end = 3 p

3 p = 6

1 p = 6 ÷ 3 = 2

Working backwards.

Amount that Tammy had after giving to Natalie on Friday
= 26 - 1 p
= 26 - 2
= $24

2 u = 24

1 u = 24 ÷ 2 = 12

Amount that Tammy had at first
= 3 u
= 3 x 12
= $36

Total amount that Tammy and Natalie had 
= 26 + 6
= $32

Amount that Natalie had at first
= 32 - 36
= $-4

Amount that Tammy had more than Natalie
= 36 - -4 
= $40

Answer(s): $40
