A sports and entertainment center has 4/5 of its total area devoted to seating.
The seats are for either general admission or reserved seating.
If 3/8 of the total area is used for general admission seating, find the fraction of the total area used for reserved seating.
:
Let t = total area
4%2F5t - 3%2F8t
the common denominator
32%2F40t - 15%2F40t = 17%2F40t for reserved seating
