Answer:

c = 55t

Step-by-step explanation:

Since there are no handling fees and the price of tickets is constant, we know the cost will be proportional to the number of tickets purchased. The generic form of an equation expressing a proportional relationship between cost (c) and number of tickets (t) is ...

c = kt

where k is the constant of proportionality (the cost per ticket). We can find k by using any of the data points given in the table. Using the first point, we have ...

110 = k·2

110/2 = k = 55 . . . . . divide by 2

Then using this value for k, the desired equation can be written ...

c = 55t
