Answer :
The number of tickets purchased is 6
Let t represent the total amount of tickets bought
Total tickets bought = $32.50 x t = $32.50t
Total convenience charge = $3.30 x t = $3.30t
Total processing charge = $5.90
Total cost of purchasing t tickets = $32.50t + $3.30t + $5.90
= $35.80t + $5.90
$220.70 = $35.80t + $5.90
combine similar terms
$220.70 - $5.90 = $35.80t
214.80 = $35.80t
Divide both sides of the equation by t
t = 6 tickets
