Let x = adults
Let 2x = students
Add together and set equal to the total number.
Answer:
Let x = no. of books
:
Cost = 12.50x + 54150
:
Revenue = 25x
:
Rev = cost
25x = 12.5x + 54150
25x - 12.50x = 54150
12.5x = 54150
x = 54150%2F12.5
x = 4332 books need to be sold to cover production costs

Check:
c = 12.50(4332) + 54150
c = 54150 + 54150
c = 108300
:
r = 25(4332)
r = 108300
