John spent ³₇ of his salary and gave $1428 to his wife. Of the remaining amount, he saved ¹₄ of it and gave ³₇ of it to his parents. He then donated ²₃ of what he had left away and gave the remaining $8 to his daughter. What was John's salary?

Spent	Wife	Saved	Parents	Donated	Daughter	Total
3 u	4 u					7 u
	$1428	1 p	3 p
			3x3	4x3
				2x4	1x4
			9 b	8 b	4 b $8

Amount that his daughter received = 4 b

4 b = 8
1 b = 8 ÷ 4 = 2

Amount of his salary given to his parents, his donations and his daughter
= 9 b + 8 b + 4 b
= 21 b
= 21 x 2
= $42

3 p = 42 
1 p = 42 ÷ 3 = 14

Amount of his salary given to his savings, his parents, his donations and his daughter
= 1 p + 3 p
= 4 p
= 4 x 14
= $56

Amount of his salary given to his wife, his savings, his parents, his donations and his daughter
= 1428 + 56
= $1484 

4 u = 1484 
1 u = 1484 ÷ 4 = 371

John's salary
= 7 u
= 7 x 371
= $2597

Answer(s): $2597
