Question

В одном куске 120 метров ткани. В другом 85 метров такой же ткани. Первый кусок на 1050 руб дороже . Сколько стоит вся ткань

Answer 1

1) 120-85=35 м разница
2) 1050:35=30 руб 1 м ткани
3) 120*30=3600 руб стоит 1 кусок
4) 85*30=2550 руб стоит 2 кусок
5) 3600+2550=6150 руб вся ткань
Ответ: 6150 рублей стоит вся ткань.

Answer 2

Calculating the Total Cost of the Fabric

To calculate the total cost of the fabric, we can use the information provided about the two pieces of fabric and their respective prices.

Let's denote: - Length of the first piece of fabric as L1 (120 meters) - Length of the second piece of fabric as L2 (85 meters) - Price of the first piece of fabric per meter as P1 (in rubles) - Price of the second piece of fabric per meter as P2 (in rubles)

Given that the first piece of fabric is 1050 rubles more expensive than the second piece, we can set up the following equation: L1 * P1 = (L2 * P2) + 1050

We can use this equation to find the individual prices and then calculate the total cost of the fabric.

Calculating the Price of Each Piece of Fabric

Using the given information, we can solve for the price of the first piece of fabric per meter (P1).

P1 = ((L2 * P2) + 1050) / L1

Now, we can substitute the given values: P1 = ((85 * P2) + 1050) / 120

Calculating the Total Cost

To find the total cost of the fabric, we can calculate the sum of the costs of the two pieces of fabric.

Total Cost = (L1 * P1) + (L2 * P2)

Substitute the value of P1 into the equation and solve for the total cost.

Total Cost = (120 * ((85 * P2) + 1050) / 120) + (85 * P2)

Simplify the equation to find the total cost.

Total Cost = (85 * P2) + 1050 + (85 * P2)

Total Cost = 170 * P2 + 1050

So, the total cost of the fabric can be calculated using the equation Total Cost = 170 * P2 + 1050.

Conclusion

The total cost of the fabric can be calculated using the equation Total Cost = 170 * P2 + 1050, where P2 is the price of the second piece of fabric per meter in rubles.
