Answer 1

Calculation of the Quantity of Tomatoes and Cucumbers

To calculate the quantity of tomatoes and cucumbers that can be bought for 80 rubles, we need to consider the prices of both vegetables and the fact that the quantity of cucumbers needed is twice that of tomatoes.

According to the information provided, the price of cucumbers is 7 rubles per kilogram, while the price of tomatoes is 12 rubles per kilogram.

Let's assume that x represents the quantity of tomatoes in kilograms. Since the quantity of cucumbers needed is twice that of tomatoes, the quantity of cucumbers can be represented as 2x.

To find the total cost of the tomatoes and cucumbers, we can use the following equation:

12x + 7(2x) = 80

Simplifying the equation:

12x + 14x = 80

26x = 80

Solving for x:

x = 80 / 26

x ≈ 3.08

Therefore, approximately 3.08 kilograms of tomatoes can be bought for 80 rubles.

To find the quantity of cucumbers, we can substitute the value of x into the equation:

2x ≈ 2 * 3.08 ≈ 6.16

Therefore, approximately 6.16 kilograms of cucumbers can be bought for 80 rubles.

Answer:

For 80 rubles, you can buy approximately 3.08 kilograms of tomatoes and 6.16 kilograms of cucumbers.

Please note that the calculations are approximate and may vary slightly depending on the actual prices and quantities available at the time of purchase.
