So this is going to be a linear equation, you can tell by seeing the growth being the same between days 15 and 20 & 33 and 38. We will be using the 
format, where m = slope and b = y-intercept.
The equation to solve for the slope is
. You can use any two ordered pairs on this list. I'll be using 15 and 20.
45 is the slope.
To solve for the y-intercept, plug in 45 in the m variable and any ordered pair into the x and y variable spot. For this, I'll be using (15, 815)
Now putting the equation together (
) we can plug in 26 into the x variable and solve.
In short, the answer is B. 1,310 feet.
