Question

The equation c = 8t+4 models the total cost of a concert. C represents the total cost after paying for tickets(t) and a processing fee. How much do tickets cost?

Answer 1

Answer: 8 dollars

This is because 8 is the slope to represent the rate of change. Each time t goes up by 1, the cost goes up by $8.

If t = 0, then C = 4

If t = 1, then C = 12 to represent an increase of $8

If t = 2, then C = 20, and so on.
