Sean spent ³₅ of his salary and gave $621 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₁₀ of it to his siblings. He then donated ²₃ of what he had left away and gave the remaining $35 to his son. What was Sean's salary?

Spent	Wife	Saved	Siblings	Donated	Son	Total
3 u	2 u					5 u
	$621	1 p	2 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $35

Amount that his son received = 7 b

7 b = 35
1 b = 35 ÷ 7 = 5

Amount of his salary given to his siblings, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 5
= $150

2 p = 150 
1 p = 150 ÷ 2 = 75

Amount of his salary given to his savings, his siblings, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 75
= $225

Amount of his salary given to his wife, his savings, his siblings, his donations and his son
= 621 + 225
= $846 

2 u = 846 
1 u = 846 ÷ 2 = 423

Sean's salary
= 5 u
= 5 x 423
= $2115

Answer(s): $2115
