Glen spent ³₅ of his salary and gave $437 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ⁴₉ of it to his grandparents. He then donated ²₃ of what he had left away and gave the remaining $10 to his son. What was Glen's salary?

Spent	Wife	Saved	Grandparents	Donated	Son	Total
3 u	2 u					5 u
	$437	1 p	2 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 grandparents, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 2
= $54

2 p = 54 
1 p = 54 ÷ 2 = 27

Amount of his salary given to his savings, his grandparents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 27
= $81

Amount of his salary given to his wife, his savings, his grandparents, his donations and his son
= 437 + 81
= $518 

2 u = 518 
1 u = 518 ÷ 2 = 259

Glen's salary
= 5 u
= 5 x 259
= $1295

Answer(s): $1295
