Amount that his son received = 7 b
7 b = 28
1 b = 28 ÷ 7 = 4
Amount of his salary given to his brothers, his donations and his son
= 9 b + 14 b + 7 b
= 30 b
= 30 x 4
= $120
4 p = 120
1 p = 120 ÷ 4 = 30
Amount of his salary given to his savings, his brothers, his donations and his son
= 1 p + 4 p
= 5 p
= 5 x 30
= $150
Amount of his salary given to his wife, his savings, his brothers, his donations and his son
= 778 + 150
= $928
2 u = 928
1 u = 928 ÷ 2 = 464
Julian's salary
= 5 u
= 5 x 464
= $2320
Answer(s): $2320
