Hi i have a couple of questions which i am extremely struggling on and hope you can help

1. In the kingdom of transylvania the cost of maintaing the royal family is directly proportional of the number of members over the age of 18 years. In 1996 there were 12 members and the cost was £9 million.

In 1976 there were 15 members: what will the cost be?

In 1994 after a rather nasty accident the cost had reduced to £2.25 million. How many members of the royal family were left?

Thank you your help would be most appreciated
