a) Let f be the cost of each ticket. We know that 2 tickets cost a total of $24.95, so therefore we have this equation:
2f = 24.95
b) Solve this equation by dividing both sides by 2:
f = 12.475
This value isn't possible with money so to make it realistic, we'll round to the nearest cent:
f = $12.48
c) We're ordering one more ticket, so we'll just add f to our total cost:
64.50 + f
= 64.50 + 12.48
= $76.98
