Tim spent ³₇ of his salary and gave $799 to his wife. Of the remaining amount, he saved ¹₅ of it and gave ⁵₁₂ of it to his siblings. He then donated ²₃ of what he had left away and gave the remaining $63 to his son. What was Tim's salary?

Spent	Wife	Saved	Siblings	Donated	Son	Total
3 u	4 u					7 u
	$799	1 p	4 p
			5x3	7x3
				2x7	1x7
			15 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 siblings, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 9
= $324

4 p = 324 
1 p = 324 ÷ 4 = 81

Amount of his salary given to his savings, his siblings, his donations and his son
= 1 p + 4 p
= 5 p
= 5 x 81
= $405

Amount of his salary given to his wife, his savings, his siblings, his donations and his son
= 799 + 405
= $1204 

4 u = 1204 
1 u = 1204 ÷ 4 = 301

Tim's salary
= 7 u
= 7 x 301
= $2107

Answer(s): $2107
