The number of stores that the company owns (y) isrepresented in the equation.

y=459x + 41

where xis the number of years since1990

Use the equation to predict how many stores the company will own in 2030.

I have come to the answer by inserting 40 as X since that is the amount of years from

1990 to 2030. I then multiply 459(the amount of stores added per year) and 40 to get 18360,

then I add the amount of initial stores in 1990 which is 41, so 18360+41 which equals 18401.

Did I work out the problem correctly?
