George spent ³₇ of his salary and gave $1669 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₇ of it to his brothers. He then donated ²₃ of what he had left away and gave the remaining $40 to his daughter. What was George's salary?

Spent	Wife	Saved	Brothers	Donated	Daughter	Total
3 u	4 u					7 u
	$1669	1 p	2 p
			3x3	4x3
				2x4	1x4
			9 b	8 b	4 b $40

Amount that his daughter received = 4 b

4 b = 40
1 b = 40 ÷ 4 = 10

Amount of his salary given to his brothers, his donations and his daughter
= 9 b + 8 b + 4 b
= 21 b
= 21 x 10
= $210

2 p = 210 
1 p = 210 ÷ 2 = 105

Amount of his salary given to his savings, his brothers, his donations and his daughter
= 1 p + 2 p
= 3 p
= 3 x 105
= $315

Amount of his salary given to his wife, his savings, his brothers, his donations and his daughter
= 1669 + 315
= $1984 

4 u = 1984 
1 u = 1984 ÷ 4 = 496

George's salary
= 7 u
= 7 x 496
= $3472

Answer(s): $3472
