The price of the goods was reduced by 8%, and then by another 4 times. How much has the original price of the product dropped?

Let’s introduce the variable right away.

Let a be the initial price of the product.

After the first drop, the price became equal to:

a * (1 – 0.08) = 0.92 * a;

After the second decline, the price became equal to:

0.92 * a * 1/4 = 0.23 * a.

Let’s find the percentage by which the value of the price of the product fell:

a – 0.23 * a = 0.77 * a.

Answer: The price of the product has decreased by 77%.
