Question

The cost, in millions of dollars, of a 30-second television ad during the Super Bowl in the years 1980 to 2000 can be approximated by C(t) = 0.044t + 0.222 million dollars (0 ≤ t ≤ 20) (t = 0 represents 1980).† What was the average cost of a Super Bowl ad during the given period?

Answer 1

Average = $0.662 million dollars

Explanation:

C(t) = 0.044t + 0.222 million dollars for (0 ≤ t ≤ 20) (t = 0 represents 1980)

C(0) = 0.044*(0) + 0.222 million dollars for 1980

C(0) = $0.222 million

C(20) = 0.044*(20) + 0.222 million dollars

C(20) = 0.88 + 0.222 million dollars

C(20) = 1.102 million dollars

Average = ($0.222 + 1.102)/2 million dollars

Average = $0.662 million dollars
