Calculating the Maximum Number of Batteries

To calculate the maximum number of batteries that can be purchased for 160 rubles during a sale with a 6% discount, we need to consider the price of a single battery and the discount.

The price of a battery is given as 22 rubles and 70 kopeks. To simplify the calculation, we can convert the price to a decimal value. 1 ruble is equal to 100 kopeks, so 70 kopeks is equal to 0.70 rubles.

Therefore, the price of a single battery is 22.70 rubles.

Next, we need to calculate the discount. The discount is given as 6%. To calculate the discounted price, we can multiply the original price by (100% - discount percentage).

Discounted price = 22.70 rubles * (100% - 6%) = 22.70 rubles * 94% = 21.358 rubles.

Now, we can calculate the maximum number of batteries that can be purchased for 160 rubles.

Max number of batteries = 160 rubles / 21.358 rubles ≈ 7.50 batteries.

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

Therefore, the maximum number of batteries that can be purchased for 160 rubles during the sale is 7 batteries.

Please note that the calculated value is an approximation and may vary depending on the rounding method used.
