Answer:

  • y = 260x + 700
  • $5900

Step-by-step explanation:

We can describe it as a linear function with points of:

  • (5, 2000) and (15, 4600)

Slope intercept formula:

  • y = mx +b

Finding the slope using the two given points:

  • m = (4600-2000)/(15-5) = 2600/10 = 260

Finding b:

  • 2000 = 5*260 + b
  • b = 2000 - 1300 = 700

Formula obtained:

  • y = 260x + 700

For x = 20, value of y is:

  • y = 260*20 + 700 = 5200+700 = $5900
