Jack spent ²₅ of his salary and gave $588 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ⁵₁₂ of it to his siblings. He then donated ²₃ of what he had left away and gave the remaining $56 to his son. What was Jack's salary?

Spent	Wife	Saved	Siblings	Donated	Son	Total
2 u	3 u					5 u
	$588	1 p	2 p
			5x3	7x3
				2x7	1x7
			15 b	14 b	7 b $56

Amount that his son received = 7 b

7 b = 56
1 b = 56 ÷ 7 = 8

Amount of his salary given to his siblings, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 8
= $288

2 p = 288 
1 p = 288 ÷ 2 = 144

Amount of his salary given to his savings, his siblings, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 144
= $432

Amount of his salary given to his wife, his savings, his siblings, his donations and his son
= 588 + 432
= $1020 

3 u = 1020 
1 u = 1020 ÷ 3 = 340

Jack's salary
= 5 u
= 5 x 340
= $1700

Answer(s): $1700
