The marketing director of the Krehlik Corporation has used historical sales data on the hand-embroidered tablecloths it imports from Hungary to conduct a regression analysis, with the following result: q = -2 * p + $263, where q = slope * p + MWB.

What will the percentage decrease in demand be if the price is increased by 10%?
