Amount that his daughter received = 7 b
7 b = 49
1 b = 49 ÷ 7 = 7
Amount of his salary given to his parents, his donations and his daughter
= 15 b + 14 b + 7 b
= 36 b
= 36 x 7
= $252
2 p = 252
1 p = 252 ÷ 2 = 126
Amount of his salary given to his savings, his parents, his donations and his daughter
= 1 p + 2 p
= 3 p
= 3 x 126
= $378
Amount of his salary given to his wife, his savings, his parents, his donations and his daughter
= 603 + 378
= $981
3 u = 981
1 u = 981 ÷ 3 = 327
Ivan's salary
= 5 u
= 5 x 327
= $1635
Answer(s): $1635
