Assume that the annual widget sales match the annual widget demand, and construct a model for revenue using the model for price that you found in the Price section.

Find the model for revenueR(x), whereR(x) is the total annual revenue in dollars forxwidgets sold, and write it asR(x)=ax²+bx+c.

I found the value of a and b but I cant find the value of c.

Use the revenue modelR(x)=ax²+bx+c

ComputeR(45)
