Amount that his son received = 5 b
5 b = 10
1 b = 10 ÷ 5 = 2
Amount of his salary given to his brothers, his donations and his son
= 12 b + 10 b + 5 b
= 27 b
= 27 x 2
= $54
2 p = 54
1 p = 54 ÷ 2 = 27
Amount of his salary given to his savings, his brothers, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 27
= $81
Amount of his salary given to his wife, his savings, his brothers, his donations and his son
= 864 + 81
= $945
3 u = 945
1 u = 945 ÷ 3 = 315
Vincent's salary
= 7 u
= 7 x 315
= $2205
Answer(s): $2205
