A graphing calculator can do a linear regression on these points very easily. The y-intercept is 107.
_____
If you want to do this by hand, you can use the 2-point form of the equation for a line, then evaluate for x=0.
.. y = (100 -102)/(35 -25)*(x -25) +102
.. y =-2/10*(0 -25) +102
.. y = 107

Answer:
(2.5,5)
Step-by-step explanation:
The given function are and
From the graph the two functions intersects at one point.
The point where they met is where the exponential function begins to exceed the quadratic function.
We can estimate this point from the graph as (2.25,4.76).
The closest to this point is (2.5,5)
We can set up an inequality.
Subtract 119.75 to both sides:
Divide 2.25 to both sides:
So the maximum number of pastries that can be baked each day is 169.
Subtract 119.75 to both sides:
Divide 2.25 to both sides:
So the maximum number of pastries that can be baked each day is 169.
