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?

• MATHS -

456 / 2 = 228

( 228 Adult + 456 Child ) * 21 \$ =

228 * 21 \$ = 4,788 \$

6 Adult * 10 \$ = 60 \$

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