Aki’s Bicycle has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)=-0.2x^2-0.1x+9.743, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle? They should build? bicycles
With minus signs in front of both of the first two terms, the average cost keeps decreasing with increasing x.
Are you sure you copied the equation correctly?
