Answer 3

Calculation of the Maximum Number of Shampoo Bottles

To calculate the maximum number of shampoo bottles that can be purchased during a sale with a 20% discount, we need to consider the original price of the shampoo bottle and the available budget.

Given that the price of one shampoo bottle is 100 rubles and the budget is 1100 rubles, we can calculate the maximum number of bottles as follows:

1. Calculate the discounted price of one shampoo bottle: - Original price: 100 rubles - Discount: 20% - Discounted price = Original price - (Original price * Discount) = 100 - (100 * 0.2) = 100 - 20 = 80 rubles.

2. Calculate the maximum number of bottles that can be purchased: - Available budget: 1100 rubles - Maximum number of bottles = Available budget / Discounted price = 1100 / 80 = 13.75. - Since we cannot purchase a fraction of a bottle, we round down to the nearest whole number. - Therefore, the maximum number of bottles that can be purchased is 13 bottles.

Answer: The maximum number of shampoo bottles that can be purchased with a budget of 1100 rubles during a sale with a 20% discount is 13 bottles.
