So, based on the problem, we know that the value of x is the number of years since 2000. If x is 5 as suggested in the problem, then the year is 2005, which means we will have to type in an answer in the box for choice b.
So, now to find the cost of agricultural exports, we can use the equation provided.
E(x) = 1.1x - 1.47
E(5) = 1.1(5) - 1.47
E(5) = 5.5 - 1.47
E(5) = 4.03
