Sean spent ⁴₇ of his salary and gave $828 to his wife. Of the remaining amount, he saved ¹₄ 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 daughter. What was Sean's salary?

Spent	Wife	Saved	Grandparents	Donated	Daughter	Total
4 u	3 u					7 u
	$828	1 p	3 p
			4x3	5x3
				2x5	1x5
			12 b	10 b	5 b $40

Amount that his daughter received = 5 b

5 b = 40
1 b = 40 ÷ 5 = 8

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

3 p = 216 
1 p = 216 ÷ 3 = 72

Amount of his salary given to his savings, his grandparents, his donations and his daughter
= 1 p + 3 p
= 4 p
= 4 x 72
= $288

Amount of his salary given to his wife, his savings, his grandparents, his donations and his daughter
= 828 + 288
= $1116 

3 u = 1116 
1 u = 1116 ÷ 3 = 372

Sean's salary
= 7 u
= 7 x 372
= $2604

Answer(s): $2604
