Billy spent ⁴₇ of his salary and gave $786 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₁₀ of it to his parents. He then donated ²₃ of what he had left away and gave the remaining $14 to his son. What was Billy's salary?

Spent	Wife	Saved	Parents	Donated	Son	Total
4 u	3 u					7 u
	$786	1 p	2 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $14

Amount that his son received = 7 b

7 b = 14
1 b = 14 ÷ 7 = 2

Amount of his salary given to his parents, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 2
= $60

2 p = 60 
1 p = 60 ÷ 2 = 30

Amount of his salary given to his savings, his parents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 30
= $90

Amount of his salary given to his wife, his savings, his parents, his donations and his son
= 786 + 90
= $876 

3 u = 876 
1 u = 876 ÷ 3 = 292

Billy's salary
= 7 u
= 7 x 292
= $2044

Answer(s): $2044
