Answer 1

The formula is (old price - new price) / (old price) and multiply it by 100

Old price os 18000

New price is 14700

Hence, % decrease is = $\frac{18000-14700}{18000}*100$

Basically, old price - new price is actually the decrease in price, which is already given

% decrease is = $\frac{3300}{18000}*100$

                       = $\frac{330}{18}$

                       = 18.33 %

Hence there is a 18.33 % dercrease in price
