C = 10t + 8, C = 12t is the set of equations used to model the situation.
Given that,
Online orders for concert tickets are $10 each, but there is a $8 service fee for each purchase. If you purchase your tickets the night of the show at the door, they cost $12 apiece.
Complete the sentence ( Let C be the total cost and let t be the number of tickets).
Online ticket purchases cost $10 plus an extra $8 service fee.
Consequently, total cost,C = 10t + 8
At the door, tickets are $12.
Consequently, total cost, C = 12t.
The equations used to model the situation are as follows:
C = 10t + 8
C = 12t
