Mark spent ⁴₇ of his salary and gave $1365 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 $10 to his son. What was Mark's salary?

Spent	Wife	Saved	Brothers	Donated	Son	Total
4 u	3 u					7 u
	$1365	1 p	3 p
			4x3	5x3
				2x5	1x5
			12 b	10 b	5 b $10

Amount that his son received = 5 b

5 b = 10
1 b = 10 ÷ 5 = 2

Amount of his salary given to his brothers, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 2
= $54

3 p = 54 
1 p = 54 ÷ 3 = 18

Amount of his salary given to his savings, his brothers, his donations and his son
= 1 p + 3 p
= 4 p
= 4 x 18
= $72

Amount of his salary given to his wife, his savings, his brothers, his donations and his son
= 1365 + 72
= $1437 

3 u = 1437 
1 u = 1437 ÷ 3 = 479

Mark's salary
= 7 u
= 7 x 479
= $3353

Answer(s): $3353
