Question

Suppose the sales of a particular brand of appliance are modeled by the linear

function S(x) = 200x + 3700, where S(x) represents the number of sales in year x, with x = 0
corresponding to 2002. Use this model to predict the number of sales in 2020.

Answer 1

7300 sales in the year 2020

Explanation:

Notice that if the year 2002 represents the year zero, then the years 2020 is:

2020-2002=18 (year number 18).

Now we can simply use the given expression for year "x" to evaluate what the sales would be in the 18th year:

`S(18)=200 * (18) +3700=7300`

Therefore the number of sales would be 7300 in the year 2020 according to this model.
