D. 1 cup.

Step-by-step explanation:

We have been given an image of a graph that shows the amount of granulated sugar, in cups, in a bakery stock room and the number of cakes created.

First of all let us find the equation of line of best fit in slope-intercept form of equation (y=mx+b) , where, m represents slope of line and b represents y-intercept.

Let us find the slope of line using slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}$ , where,

y_2-y_1 = Difference between two y-coordinates,

x_2-x_1 = Difference between two x-coordinates of same y-coordinates.

Upon substituting coordinates of points (4,20) and (10,11) in slope formula we will get,

$m=\frac{11-20}{10-4}$

$m=\frac{-9}{6}$

m=-1.5

We can see that y-intercept of our given equation is approximately 25.4.

So equation of line of best fit will be y=-1.5x+25.4 .

Let us substitute x= 16 in our given equation to find the number of cups of sugar.

y=-1.5*16+25.4

y=-24+25.4

$y=1.4\approx 1$

Therefore, approximately 1 cup will be left after the baker has made 16 cakes and option D is the correct choice.
