Answer 2

Calculation of the Selling Price

To determine the selling price of a pound of mixed tea, we need to calculate the total cost of the tea and add the desired profit of 23 rubles.

Let's break down the given information:

- 7 pounds of tea were mixed and purchased at a rate of 2 rubles per pound. - 6 pounds of tea were mixed and purchased at a rate of 2 rubles and 50 kopeks per pound. - 5 pounds of tea were mixed and purchased at a rate of 4 rubles per pound.

To calculate the total cost of the tea, we can multiply the weight of each batch by its respective price and sum them up:

Total cost = (7 pounds * 2 rubles/pound) + (6 pounds * 2 rubles and 50 kopeks/pound) + (5 pounds * 4 rubles/pound)

Now, let's convert the price of 2 rubles and 50 kopeks to rubles. Since 1 ruble is equal to 100 kopeks, 50 kopeks is equal to 0.5 rubles. Therefore, the price of 2 rubles and 50 kopeks is 2.5 rubles.

Total cost = (7 pounds * 2 rubles/pound) + (6 pounds * 2.5 rubles/pound) + (5 pounds * 4 rubles/pound)

Now, we can calculate the total cost:

Total cost = (7 * 2) + (6 * 2.5) + (5 * 4) rubles

Total cost = 14 + 15 + 20 rubles

Total cost = 49 rubles

To determine the selling price, we need to add the desired profit of 23 rubles to the total cost:

Selling price = Total cost + Profit

Selling price = 49 rubles + 23 rubles

Selling price = 72 rubles

Therefore, the trader should sell a pound of mixed tea at a price of 72 rubles in order to make a profit of 23 rubles.
