Amount that his son received = 7 b
7 b = 28
1 b = 28 ÷ 7 = 4
Amount of his salary given to his parents, his donations and his son
= 15 b + 14 b + 7 b
= 36 b
= 36 x 4
= $144
2 p = 144
1 p = 144 ÷ 2 = 72
Amount of his salary given to his savings, his parents, his donations and his son
= 1 p + 2 p
= 3 p
= 3 x 72
= $216
Amount of his salary given to his wife, his savings, his parents, his donations and his son
= 1041 + 216
= $1257
3 u = 1257
1 u = 1257 ÷ 3 = 419
Liam's salary
= 5 u
= 5 x 419
= $2095
Answer(s): $2095
