Xavier spent ³₅ of his salary and gave $318 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 $42 to his daughter. What was Xavier's salary?

Spent	Wife	Saved	Siblings	Donated	Daughter	Total
3 u	2 u					5 u
	$318	1 p	2 p
			5x3	7x3
				2x7	1x7
			15 b	14 b	7 b $42

Amount that his daughter received = 7 b

7 b = 42
1 b = 42 ÷ 7 = 6

Amount of his salary given to his siblings, his donations and his daughter
= 15 b + 14 b + 7 b
= 36 b
= 36 x 6
= $216

2 p = 216 
1 p = 216 ÷ 2 = 108

Amount of his salary given to his savings, his siblings, his donations and his daughter
= 1 p + 2 p
= 3 p
= 3 x 108
= $324

Amount of his salary given to his wife, his savings, his siblings, his donations and his daughter
= 318 + 324
= $642 

2 u = 642 
1 u = 642 ÷ 2 = 321

Xavier's salary
= 5 u
= 5 x 321
= $1605

Answer(s): $1605
