Current sales are $80,000 per year. Advertising expense is $6,500 per year. The owner believes an increase of 10% in advertising over the next 3 years will result in an increase of $8,000 in annual sales. What is the net present value of his decision if he uses 4% as his interest rate?

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
