Liam spent ⁴₇ of his salary and gave $689 to his wife. Of the remaining amount, he saved ¹₄ of it and gave ³₁₀ of it to his grandparents. He then donated ²₃ of what he had left away and gave the remaining $28 to his daughter. What was Liam's salary?

Spent	Wife	Saved	Grandparents	Donated	Daughter	Total
4 u	3 u					7 u
	$689	1 p	3 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $28

Amount that his daughter received = 7 b

7 b = 28
1 b = 28 ÷ 7 = 4

Amount of his salary given to his grandparents, his donations and his daughter
= 9 b + 14 b + 7 b
= 30 b
= 30 x 4
= $120

3 p = 120 
1 p = 120 ÷ 3 = 40

Amount of his salary given to his savings, his grandparents, his donations and his daughter
= 1 p + 3 p
= 4 p
= 4 x 40
= $160

Amount of his salary given to his wife, his savings, his grandparents, his donations and his daughter
= 689 + 160
= $849 

3 u = 849 
1 u = 849 ÷ 3 = 283

Liam's salary
= 7 u
= 7 x 283
= $1981

Answer(s): $1981
