Ryan spent ³₇ of his salary and gave $1188 to his wife. Of the remaining amount, he saved ¹₃ of it and gave ⁵₁₂ of it to his sisters. He then donated ²₃ of what he had left away and gave the remaining $28 to his son. What was Ryan's salary?

Spent	Wife	Saved	Sisters	Donated	Son	Total
3 u	4 u					7 u
	$1188	1 p	2 p
			5x3	7x3
				2x7	1x7
			15 b	14 b	7 b $28

Amount that his son received = 7 b

7 b = 28
1 b = 28 ÷ 7 = 4

Amount of his salary given to his sisters, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 4
= $144

2 p = 144 
1 p = 144 ÷ 2 = 72

Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 72
= $216

Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 1188 + 216
= $1404 

4 u = 1404 
1 u = 1404 ÷ 4 = 351

Ryan's salary
= 7 u
= 7 x 351
= $2457

Answer(s): $2457
