Answer:
The school sells 625 tickets.
Solution:
Let us assume that total x number of tickets are sold by the school.
As given in the problem,
Cost of 5 tickets is \20 [tex]\$20[/tex]
So the cost of 1 ticket is [tex]\left(\frac{20}{5}\right) = \$4[/tex]
Then the cost of x tickets = [tex]\$4x[/tex]
As given the total revenue is [tex]\$2500[/tex],
So,
[tex]4 x=2500[/tex]
[tex]x=\left(\frac{2500}{4}\right)=625[/tex]
The school sell total 625 tickets.
