Amount that his son received = 4 b
4 b = 16
1 b = 16 ÷ 4 = 4
Amount of his salary given to his sisters, his donations and his son
= 9 b + 8 b + 4 b
= 21 b
= 21 x 4
= $84
3 p = 84
1 p = 84 ÷ 3 = 28
Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 3 p
= 4 p
= 4 x 28
= $112
Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 856 + 112
= $968
2 u = 968
1 u = 968 ÷ 2 = 484
Andy's salary
= 5 u
= 5 x 484
= $2420
Answer(s): $2420
