The average cost of a movie ticket is
If the cost is increasing
per year, in how many years will the cost double?
Construct a representation of this scenario using the generic exponential equation:
(the number of years): years
What is the average rate of change of the cost of a movie ticket over the interval of the next
years? Explain what the average rate of change means in this context.
The average rate of change is the same as asking for the slope of a line.
What is the equation for slope, if the price is
and time is ?
