Calculating the Price of Wool

To calculate the price of 1 meter of wool, we can use the given information that 80 cm of silk and 2.5 meters of wool were purchased for 336 rubles and 40 kopecks, and the cost of 1 meter of silk is 58 rubles.

First, let's convert the price of the silk and wool into a common unit, rubles.

1. The cost of 80 cm of silk: - 80 cm = 0.8 meters - Cost of 0.8 meters of silk = 0.8 * 58 = 46.4 rubles

2. The cost of 2.5 meters of wool: - Cost of 2.5 meters of wool = 336 rubles 40 kopecks - 46.4 rubles - Cost of 2.5 meters of wool = 336.4 - 46.4 = 290 rubles

Now, we can calculate the price of 1 meter of wool.

Calculating the Price of 1 Meter of Wool

To find the price of 1 meter of wool, we divide the total cost of 2.5 meters of wool by 2.5.

Price of 1 meter of wool = Total cost of 2.5 meters of wool / 2.5 Price of 1 meter of wool = 290 / 2.5 Price of 1 meter of wool = 116 rubles

Therefore, the price of 1 meter of wool is 116 rubles.
