Question

Помогите пожалуйста!!!! За 1,8 кг. огурцов и 2,4 кг помидор заплатили 2, 16 тысяч рублей. Известно что 1 кг помидоров дороже 1 кг огурцов, на 0,2 тысяч рублей. Сколько стоит 1 кг помидоров?

Answer 1

Пусть х - стоит один кг помидоров. Тогда (х-0,2) - стоит кг огурцов.
 Тогда из условия имеем уравнение:
 1,8(х-0,2) + 2,4х = 2,16
 4,2х = 2,52
 х = 0,6
 Ответ: 600 руб (0,6 тыс. руб).

Answer 2

Calculation of Tomato Price

To calculate the price of 1 kg of tomatoes, we can use the given information about the prices of cucumbers and tomatoes and their respective weights.

Let's denote the price of 1 kg of cucumbers as C and the price of 1 kg of tomatoes as T.

From the given information, we know that: - The total cost of 1.8 kg of cucumbers and 2.4 kg of tomatoes is 2.16 thousand rubles. - The price of 1 kg of tomatoes is 0.2 thousand rubles more expensive than 1 kg of cucumbers.

Using these facts, we can set up the following equations:

Equation 1: 1.8C + 2.4T = 2.16 Equation 2: T = C + 0.2

To solve this system of equations, we can substitute Equation 2 into Equation 1:

1.8C + 2.4(C + 0.2) = 2.16

Simplifying the equation:

1.8C + 2.4C + 0.48 = 2.16 4.2C = 1.68 C = 1.68 / 4.2 C ≈ 0.4

Now that we have the value of C, we can substitute it back into Equation 2 to find the value of T:

T = 0.4 + 0.2 T ≈ 0.6

Therefore, the price of 1 kg of tomatoes is approximately 0.6 thousand rubles.

Please note that the calculations are approximate due to rounding.
