Alecsey [184]

Answer:

Step-by-step explanation:

Given, Annual passenger revenue for the years 1980 to 2000 id=s modeled with the formula $R=-40|x-11|+990$ .

Here, $R$ is the annual revenue in millions of dollars, $x$ is the number of years since January 1, 1980.

Revenue in a year was $ 790 million.

So, $R=790\\-40|x-11|+990=790\\40|x-11|=200\\|x-11|=5\\x-11=5\text{ (or) }x-11=-5\\x=16\text{ (or) }x=6$

So, after 6 yrs and 16 yrs from January 1, 1980, the Passenger revenue equals $ 790 million.

∴ Passenger revenue equals $ 790 million in 1986 and 1996.
