Daniel spent ⁴₇ of his salary and gave $1152 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ³₁₀ of it to his grandparents. He then donated ²₃ of what he had left away and gave the remaining $49 to his son. What was Daniel's salary?

Spent	Wife	Saved	Grandparents	Donated	Son	Total
4 u	3 u					7 u
	$1152	1 p	2 p
			3x3	7x3
				2x7	1x7
			9 b	14 b	7 b $49

Amount that his son received = 7 b

7 b = 49
1 b = 49 ÷ 7 = 7

Amount of his salary given to his grandparents, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 7
= $210

2 p = 210 
1 p = 210 ÷ 2 = 105

Amount of his salary given to his savings, his grandparents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 105
= $315

Amount of his salary given to his wife, his savings, his grandparents, his donations and his son
= 1152 + 315
= $1467 

3 u = 1467 
1 u = 1467 ÷ 3 = 489

Daniel's salary
= 7 u
= 7 x 489
= $3423

Answer(s): $3423
