You are a member of the fund-raising committee for your school. The committee is sponsoring a fair. Each member of the committee has agreed to sell 50 tickets to the fair. Student tickets are $3 each and adult tickets are $5 each. Let t represent the number of student tickets that you sell. Write and simplify an expression in terms of t for the total amount of money you raise for selling all 50 tickets. Then use the expression to determine how much money you will raise if you sell all 50 tickets and 28 of those are student tickets.
