old question, answering to close.

let x be the # of cheaper tickets and y the # of more expensive tickets.

you can make a system of two equations to solve for these two unknowns.

since there are 30 tickets, x + y = 30
the cheaper tickets are $0.60 and the more expensive tickets are $1. so the total revenue would be 0.6*x + 1*y = $22.00

solve the system for x
