Question

define variables, write an equation, and then use the equation in the solving process. 

Suppose the sales of a particular brand of appliance satisfy the relationship , S(x)=200x+5100, where S(x) represents the number of sales in year x, with x=0 corresponding to 1982. In what year would the sales be 8100?

Answer 1

8100 = 200x + 5100

 

3000 = 200x

 

x = 3000/200 = 30/2 = 15

 

 

1982 + 15 = 1997
