A price is increased by 10% and then decreased by 10%. What is the net percentage change in price?
A0% change
B1% increase
C1% decrease
D2% decrease
Explanation
Let initial price = 100. After 10% increase = 110. After 10% decrease = 110 – (0.10 * 110) = 99. Net change = 99 – 100 = -1 (1% decrease).
