Answer 1

Calculation of Equivalent Discount

To calculate the equivalent discount when the price of a product is reduced by a certain percentage multiple times, we can use the following formula:

Equivalent Discount = 100 - (100 - Percentage1) * (100 - Percentage2) / 100

In this case, the price of the groats (крупа) was reduced by 10% on Wednesday and then reduced by another 10% on Friday. Let's calculate the equivalent discount:

Equivalent Discount = 100 - (100 - 10) * (100 - 10) / 100

Calculating this expression, we find that the equivalent discount is 19%. Therefore, the equivalent one-time discount would be 19%.
