Answer 2

Calculation of the Maximum Number of Batteries

To calculate the maximum number of batteries that can be purchased with a given budget during a sale, we need to consider the price of each battery and the discount applied.

Given: - Price of one battery: 24 rubles and 20 kopeks - Budget: 180 rubles - Discount: 24%

To find the maximum number of batteries, we can divide the budget by the discounted price of one battery.

First, let's calculate the discounted price of one battery: - Discounted price = Price of one battery - (Discount percentage * Price of one battery) - Discounted price = 24.20 - (0.24 * 24.20) = 24.20 - 5.808 = 18.392 rubles

Next, let's calculate the maximum number of batteries that can be purchased: - Maximum number of batteries = Budget / Discounted price - Maximum number of batteries = 180 / 18.392 = 9.78

Since we cannot purchase a fraction of a battery, we need to round down the maximum number of batteries to the nearest whole number.

Therefore, the maximum number of batteries that can be purchased with a budget of 180 rubles during the sale, with a 24% discount, is 9 batteries.

Please note that the price calculation has been rounded to one kopek, as specified in the question.
