Calculation of the Maximum Number of Detergent Packs

To calculate the maximum number of detergent packs that can be purchased with a given budget during a sale with a 10% discount, we need to follow these steps:

1. Determine the price of a single detergent pack: 52 rubles and 30 kopeks. 2. Apply the 10% discount to the price: 52.30 * 0.10 = 5.23 rubles. 3. Subtract the discounted price from the original price to get the final price per pack: 52.30 - 5.23 = 47.07 rubles. 4. Divide the total budget of 220 rubles by the final price per pack: 220 / 47.07 = 4.67 packs.

Since we cannot purchase a fraction of a pack, we need to round down to the nearest whole number. Therefore, the maximum number of detergent packs that can be purchased with a budget of 220 rubles during the sale is 4 packs.

Please note that the calculation assumes that the price of each detergent pack remains constant during the sale and that the discount is applied uniformly to all packs.
