An amateur drama group hire a theatre for their production. They expect to sell all 850 tickets, some at $12 and the rest at $8. The group require the ticket sales to cover their $3760 production costs and to make a profit of $4000. If they are to exactly achieve this target and their expectations regarding ticket sales are correct how many of the 850 tickets should they charge $12 for and how many should they charge $8 for?

610 tickets for $8, and 240 tickets for $12.
Step-by-step explanation:
x + y = 850
8x + 12y = 7760
x = 850 - y
8(850-y) + 12y = 7760
6800 - 8y + 12y = 7760
4y = 960
y= 240
x + 240 = 850
x= 610
