Amount that his son received = 7 b
7 b = 35
1 b = 35 ÷ 7 = 5
Amount of his salary given to his grandparents, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 5
= $150
2 p = 150
1 p = 150 ÷ 2 = 75
Amount of his salary given to his savings, his grandparents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 75
= $225
Amount of his salary given to his wife, his savings, his grandparents, his donations and his son
= 923 + 225
= $1148
4 u = 1148
1 u = 1148 ÷ 4 = 287
Ryan's salary
= 7 u
= 7 x 287
= $2009
Answer(s): $2009
