Fred spent ⁴₇ of his salary and gave $996 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₁₀ of it to his sisters. He then donated ²₃ of what he had left away and gave the remaining $28 to his son. What was Fred's salary?

Spent	Wife	Saved	Sisters	Donated	Son	Total
4 u	3 u					7 u
	$996	1 p	2 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $28

Amount that his son received = 7 b

7 b = 28
1 b = 28 ÷ 7 = 4

Amount of his salary given to his sisters, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 4
= $120

2 p = 120 
1 p = 120 ÷ 2 = 60

Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 60
= $180

Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 996 + 180
= $1176 

3 u = 1176 
1 u = 1176 ÷ 3 = 392

Fred's salary
= 7 u
= 7 x 392
= $2744

Answer(s): $2744
