Howard spent ³₅ of his salary and gave $412 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 $40 to his son. What was Howard's salary?

Spent	Wife	Saved	Grandparents	Donated	Son	Total
3 u	2 u					5 u
	$412	1 p	2 p
			4x3	5x3
				2x5	1x5
			12 b	10 b	5 b $40

Amount that his son received = 5 b

5 b = 40
1 b = 40 ÷ 5 = 8

Amount of his salary given to his grandparents, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 8
= $216

2 p = 216 
1 p = 216 ÷ 2 = 108

Amount of his salary given to his savings, his grandparents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 108
= $324

Amount of his salary given to his wife, his savings, his grandparents, his donations and his son
= 412 + 324
= $736 

2 u = 736 
1 u = 736 ÷ 2 = 368

Howard's salary
= 5 u
= 5 x 368
= $1840

Answer(s): $1840
