Xavier spent ²₅ of his salary and gave $387 to his wife. Of the remaining amount, he saved ¹₄ of it and gave ⁴₉ of it to his brothers. He then donated ²₃ of what he had left away and gave the remaining $30 to his son. What was Xavier's salary?

Spent	Wife	Saved	Brothers	Donated	Son	Total
2 u	3 u					5 u
	$387	1 p	3 p
			4x3	5x3
				2x5	1x5
			12 b	10 b	5 b $30

Amount that his son received = 5 b

5 b = 30
1 b = 30 ÷ 5 = 6

Amount of his salary given to his brothers, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 6
= $162

3 p = 162 
1 p = 162 ÷ 3 = 54

Amount of his salary given to his savings, his brothers, his donations and his son
= 1 p + 3 p
= 4 p
= 4 x 54
= $216

Amount of his salary given to his wife, his savings, his brothers, his donations and his son
= 387 + 216
= $603 

3 u = 603 
1 u = 603 ÷ 3 = 201

Xavier's salary
= 5 u
= 5 x 201
= $1005

Answer(s): $1005
