Question

The entrance fees to the Science centre is as follows:
Adult :$ 10 Child :$7
A group package of 1 adult and 2 children can be bought at a discounted price of $21.
One day, 234 adults and 456 children visited the Science Centre. What is the minimum amount of entrance fees that the Science Centre can collect on the day?

Answer 1

456 / 2 = 228



( 228 Adult + 456 Child ) * 21 $ =

228 * 21 $ = 4,788 $



234 Adult - 228 Adult = 6 Adult

6 Adult * 10 $ = 60 $



4,788 $ + 60 $ = 4,848 $
