In 1980, the average cost of a pack of cigarettes was $0.99. In 2000, the average cost was $4.58 per pack. Find is the average rate of change of the cost of a pack of cigarettes. Create a linear equation using the year 1980 as your starting year. What value did you put in for your starting point? Round your answer to the nearest cent.
Added by Robert C.
Step 1
99 and the cost in 2000 is $4.58. Change in cost = $4.58 - $0.99 = $3.59 ** Show more…

'An average math book cost $25 in 1980 and 60 in 1995 1) give the linear equation representing the cost C in terms of the year; t where t is the number of years since 1980 2) use the equation to predict the price of math book in 2019'

The average state cigarette tax per pack (in dollars) from 2001 through 2007 is approximated by the function $$T(t)=0.43 t^{0.43} \quad(1 \leq t \leq 7)$$ where $t$ is measured in years, with $t=1$ corresponding to $2001 .$ a. Show that the average state cigarette tax per pack was increasing throughout the period in question. b. What can you say about the rate at which the average state cigarette tax per pack was increasing over the period in question?
