Amount that his son received = 7 b
7 b = 14
1 b = 14 ÷ 7 = 2
Amount of his salary given to his sisters, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 2
= $72
2 p = 72
1 p = 72 ÷ 2 = 36
Amount of his salary given to his savings, his sisters, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 36
= $108
Amount of his salary given to his wife, his savings, his sisters, his donations and his son
= 1472 + 108
= $1580
4 u = 1580
1 u = 1580 ÷ 4 = 395
Howard's salary
= 7 u
= 7 x 395
= $2765
Answer(s): $2765
