Vincent spent ²₅ of his salary and gave $531 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 $50 to his son. What was Vincent's salary?

Spent	Wife	Saved	Grandparents	Donated	Son	Total
2 u	3 u					5 u
	$531	1 p	3 p
			4x3	5x3
				2x5	1x5
			12 b	10 b	5 b $50

Amount that his son received = 5 b

5 b = 50
1 b = 50 ÷ 5 = 10

Amount of his salary given to his grandparents, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 10
= $270

3 p = 270 
1 p = 270 ÷ 3 = 90

Amount of his salary given to his savings, his grandparents, his donations and his son
= 1 p + 3 p
= 4 p
= 4 x 90
= $360

Amount of his salary given to his wife, his savings, his grandparents, his donations and his son
= 531 + 360
= $891 

3 u = 891 
1 u = 891 ÷ 3 = 297

Vincent's salary
= 5 u
= 5 x 297
= $1485

Answer(s): $1485
