Answer:
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 , where, m represents slope of line and b represents y-intercept.
Let us find the slope of line using slope formula.
, where,
= Difference between two y-coordinates,
= 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,
We can see that y-intercept of our given equation is approximately 25.4.
So equation of line of best fit will be .
Let us substitute x= 16 in our given equation to find the number of cups of sugar.
Therefore, approximately 1 cup will be left after the baker has made 16 cakes and option D is the correct choice.
