b.

Answer to Problem 69E
Final answer
Explanation of Solution
Given information:
For selected years from 1955 through 2010, the annual per capita consumption
Formula used:
The following formula is used:
Calculation :
In the given function,
The function has a maximum value when
The value of
Hence, for the year
The maximum average annual consumption can be calculated by:
Hence, the maximum annual consumption is
c.
To determine whether the health warning printed on cigarette packages from 1966 had any effect on the consumption.
c.

Answer to Problem 69E
There is no significant effect on the consumption of cigarettes after the warnings were printed on the packages in 1966.
Explanation of Solution
Given information:
For selected years from 1955 through 2010, the annual per capita consumption
The graph of the model is:
Calculation :
For the year 1966,
The consumption of cigarettes for the year 1966 can be calculated by:
Hence, it can also be seen from the graph that there is no significant effect on the consumption of cigarettes after the warnings were printed on the packages in 1966.
d.
To determine the average annual cigarette consumption per smoker in 2010 and the average daily cigarette consumption per smoker.
d.

Answer to Problem 69E
The average daily cigarette consumption per smoker in 2010 was
Explanation of Solution
Given information:
For selected years from 1955 through 2010, the annual per capita consumption
Calculation :
For the year 2010,
The consumption of cigarettes per smoker for the year 2010 can be calculated by:
Hence, the average annual cigarette consumption per smoker in 2010 was
The daily average cigarette consumption per smoker can be calculated by:
Hence, the average daily cigarette consumption per smoker in 2010 was

Can you write it (numerical method)arrow_forwardThere are three options for investing $1150. The first earns 10% compounded annually, the second earns 10% compounded quarterly, and the third earns 10% compounded continuously. Find equations that model each investment growth and use a graphing utility to graph each model in the same viewing window over a 20-year period. Use the graph to determine which investment yields the highest return after 20 years. What are the differences in earnings among the three investment? STEP 1: The formula for compound interest is A = nt = P(1 + − − ) n², where n is the number of compoundings per year, t is the number of years, r is the interest rate, P is the principal, and A is the amount (balance) after t years. For continuous compounding, the formula reduces to A = Pert Find r and n for each model, and use these values to write A in terms of t for each case. Annual Model r=0.10 A = Y(t) = 1150 (1.10)* n = 1 Quarterly Model r = 0.10 n = 4 A = Q(t) = 1150(1.025) 4t Continuous Model r=0.10 A = C(t) =…arrow_forward
