George spent ⁴₇ of his salary and gave $981 to his wife. Of the remaining amount, he saved ¹₅ of it and gave ³₁₀ of it to his parents. He then donated ²₃ of what he had left away and gave the remaining $42 to his son. What was George's salary?

Spent	Wife	Saved	Parents	Donated	Son	Total
4 u	3 u					7 u
	$981	1 p	4 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $42

Amount that his son received = 7 b

7 b = 42
1 b = 42 ÷ 7 = 6

Amount of his salary given to his parents, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 6
= $180

4 p = 180 
1 p = 180 ÷ 4 = 45

Amount of his salary given to his savings, his parents, his donations and his son
= 1 p + 4 p
= 5 p
= 5 x 45
= $225

Amount of his salary given to his wife, his savings, his parents, his donations and his son
= 981 + 225
= $1206 

3 u = 1206 
1 u = 1206 ÷ 3 = 402

George's salary
= 7 u
= 7 x 402
= $2814

Answer(s): $2814
