Cinema tickets

£10 -adults
50p -o.a.p's
10p -kids

How many people can go to yhe cinema
It should cover up 100 seats altogether and it should be £100 altogether.

For example

8 adults- £80.00
27 o.a.p's-£13.50
65 kids- £ 6.50
Total total
100 people £100

Well, I think there are quite a number of solutions for that...

Equations for that would be

10x + 0.5y + 0.1z = 100 and
x + y + z = 100.

And you already gave one... :confused:
