Amount that his daughter received = 4 b
4 b = 20
1 b = 20 ÷ 4 = 5
Amount of his salary given to his brothers, his donations and his daughter
= 9 b + 8 b + 4 b
= 21 b
= 21 x 5
= $105
3 p = 105
1 p = 105 ÷ 3 = 35
Amount of his salary given to his savings, his brothers, his donations and his daughter
= 1 p + 3 p
= 4 p
= 4 x 35
= $140
Amount of his salary given to his wife, his savings, his brothers, his donations and his daughter
= 529 + 140
= $669
3 u = 669
1 u = 669 ÷ 3 = 223
Warren's salary
= 7 u
= 7 x 223
= $1561
Answer(s): $1561
