Answer 1

Calculation of the Cost per Meter of Fabric

To calculate the cost per meter of fabric, we can use the given information about the purchase of 5 meters and 9 meters of fabric, along with the remaining amount of money in each case.

Let's denote the cost per meter of fabric as x.

According to the given information: - If the owner buys 5 meters of fabric, she will have 297,000 rubles left. - If the owner buys 9 meters of the same fabric, she will have 17,000 rubles left.

To find the cost per meter of fabric, we can set up two equations based on the given information:

Equation 1: 5x + 297,000 = 0 Equation 2: 9x + 17,000 = 0

We can solve these equations to find the value of x, which represents the cost per meter of fabric.

Let's solve the equations:

Equation 1: 5x + 297,000 = 0

Equation 2: 9x + 17,000 = 0

Solving Equation 1: 5x = -297,000 x = -297,000 / 5 x = -59,400

Solving Equation 2: 9x = -17,000 x = -17,000 / 9 x = -1,888.89

Based on the calculations, we find that the cost per meter of fabric is approximately -1,888.89 rubles.

Please note that the negative value obtained for the cost per meter of fabric seems unusual. It is possible that there might be an error in the given information or the calculations.
