Albert spent ⁴₇ of his salary and gave $429 to his wife. Of the remaining amount, he saved ¹₅ of it and gave ³₁₀ of it to his parents. He then donated ²₃ of what he had left away and gave the remaining $42 to his daughter. What was Albert's salary?

Spent	Wife	Saved	Parents	Donated	Daughter	Total
4 u	3 u					7 u
	$429	1 p	4 p
			3x3	7x3
				2x7	1x7
			9 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 parents, his donations and his daughter
= 9 b + 14 b + 7 b
= 30 b
= 30 x 6
= $180

4 p = 180 
1 p = 180 ÷ 4 = 45

Amount of his salary given to his savings, his parents, his donations and his daughter
= 1 p + 4 p
= 5 p
= 5 x 45
= $225

Amount of his salary given to his wife, his savings, his parents, his donations and his daughter
= 429 + 225
= $654 

3 u = 654 
1 u = 654 ÷ 3 = 218

Albert's salary
= 7 u
= 7 x 218
= $1526

Answer(s): $1526
