Step-by-step explanation:
Given
Represent the amount of fertilizer with x and the yield with y.
So, we have:
Required:
Determine the yield (y) when fertilizer (x) is 73ft^3
Using linear interpolation, we have:
Substitute the x and y values using
and
;
We have:
Open bracket
To solve for y when x = 73.
We simply substitute 73 for x
<em>Hence, the yield for 73 cubic feet is 657 pounds</em>
Keeping in mind that, an absolute value expression is in effect a piece-wise, then
