Henry spent ³₇ of his salary and gave $1418 to his wife. Of the remaining amount, he saved ¹₅ of it and gave ⁵₁₂ of it to his grandparents. He then donated ²₃ of what he had left away and gave the remaining $42 to his daughter. What was Henry's salary?

Spent	Wife	Saved	Grandparents	Donated	Daughter	Total
3 u	4 u					7 u
	$1418	1 p	4 p
			5x3	7x3
				2x7	1x7
			15 b	14 b	7 b $42

Amount that his daughter received = 7 b

7 b = 42
1 b = 42 ÷ 7 = 6

Amount of his salary given to his grandparents, his donations and his daughter
= 15 b + 14 b + 7 b
= 36 b
= 36 x 6
= $216

4 p = 216 
1 p = 216 ÷ 4 = 54

Amount of his salary given to his savings, his grandparents, his donations and his daughter
= 1 p + 4 p
= 5 p
= 5 x 54
= $270

Amount of his salary given to his wife, his savings, his grandparents, his donations and his daughter
= 1418 + 270
= $1688 

4 u = 1688 
1 u = 1688 ÷ 4 = 422

Henry's salary
= 7 u
= 7 x 422
= $2954

Answer(s): $2954
