Seth spent ³₅ of his salary and gave $245 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₁₀ of it to his sisters. He then donated ²₃ of what he had left away and gave the remaining $63 to his son. What was Seth's salary?

Spent	Wife	Saved	Sisters	Donated	Son	Total
3 u	2 u					5 u
	$245	1 p	2 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $63

Amount that his son received = 7 b

7 b = 63
1 b = 63 ÷ 7 = 9

Amount of his salary given to his sisters, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 9
= $270

2 p = 270 
1 p = 270 ÷ 2 = 135

Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 135
= $405

Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 245 + 405
= $650 

2 u = 650 
1 u = 650 ÷ 2 = 325

Seth's salary
= 5 u
= 5 x 325
= $1625

Answer(s): $1625
