Calculation of the Maximum Number of Batteries

To calculate the maximum number of batteries that can be purchased with a discount of 24% and a budget of 180 rubles, we need to follow these steps:

1. Calculate the discounted price of a single battery: - The original price of a battery is 24 rubles and 20 kopeks. - The discount is 24%. - To calculate the discounted price, we subtract the discount amount from the original price. - The discount amount is 24% of 24 rubles and 20 kopeks. - The discounted price is the original price minus the discount amount.

2. Calculate the maximum number of batteries that can be purchased: - Divide the budget of 180 rubles by the discounted price of a single battery. - Round down the result to the nearest whole number, as we cannot purchase a fraction of a battery.

Let's perform these calculations step by step.

Calculation Steps

1. Calculate the discounted price of a single battery: - The original price of a battery is 24 rubles and 20 kopeks. - The discount is 24%. - To calculate the discount amount, we multiply the original price by the discount percentage. - The discount amount is 24% of 24 rubles and 20 kopeks. - The discount amount is calculated as follows: - 24 rubles and 20 kopeks * (24/100) = 5 rubles and 81 kopeks. - The discounted price is the original price minus the discount amount. - The discounted price is calculated as follows: - 24 rubles and 20 kopeks - 5 rubles and 81 kopeks = 18 rubles and 39 kopeks.

2. Calculate the maximum number of batteries that can be purchased: - Divide the budget of 180 rubles by the discounted price of a single battery. - The maximum number of batteries is calculated as follows: - 180 rubles / 18 rubles and 39 kopeks = 9.76 batteries. - Since we cannot purchase a fraction of a battery, we round down the result to the nearest whole number. - The maximum number of batteries that can be purchased is 9.

Answer

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