Michael spent ²₅ of his salary and gave $333 to his wife. Of the remaining amount, he saved ¹₄ of it and gave ⁵₁₂ of it to his sisters. He then donated ²₃ of what he had left away and gave the remaining $42 to his son. What was Michael's salary?

Spent	Wife	Saved	Sisters	Donated	Son	Total
2 u	3 u					5 u
	$333	1 p	3 p
			5x3	7x3
				2x7	1x7
			15 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 sisters, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 6
= $216

3 p = 216 
1 p = 216 ÷ 3 = 72

Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 3 p
= 4 p
= 4 x 72
= $288

Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 333 + 288
= $621 

3 u = 621 
1 u = 621 ÷ 3 = 207

Michael's salary
= 5 u
= 5 x 207
= $1035

Answer(s): $1035
