A group of friends, consisting of 6 adults and 6 children attend the museum. One of
the adults has a coupon for one free adult admission and one child's admission at half
price. What is the total cost for the whole group to enter the museum?

Answer 1

$63.55

Explanation:

if one of the adults has a free coupon for adult admission, then we have 5 adults

8.20 x 5 = $41

We have 6 children and one with half pay

= (5 x 4.1) + (4.1/2 )

= 20.5 + 2.05

=$22.55

41 + 22.55 = $63.55
