Question

Please help.. I don't even know where to begin with this problem.
Two years after an expansion, a company had sales of $420,000. Four years later, sales were $1,220,000. Assuming that sales and time since the expansion are related by a linear equation, determine the expected sales in another 6 years.

Answer 1

Let at time of expansion company has x
And which are increased linearly with time.so let they are increased by y per year so the linear equation should be..
x+2y=420,000
And. x+4y=1,220,000
You have two equation and two variable
Can you find x,y.

Answer 2

After you find the values of x, y
You have to find
1,220,000+6y =?
As it is asking for another 6 years after they have reached 1,220,000.

Answer 3

its asking how long and ho much

Answer 4

so I got x=419,998 and y=200,000 I'm not sure how to put this in a sentence to answer the question.....
