Please be complete. Thank you!
The demand function is:
p = -0.01x^2 - 0.2x + 15
Where p is the wholesale unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. Determine the consumers' surplus if the wholesale unit price is $12 per tape. Rounded to the nearest cent.
