Answer 2

Calculation of the Total Cost

To determine if 900 rubles is enough to purchase 9.75 meters of atlas fabric and 10.5 meters of silk fabric, we need to calculate the total cost of both fabrics.

The price of one meter of atlas fabric is 42.8 rubles, and the price of one meter of silk fabric is 4.78 rubles cheaper. Let's calculate the cost of each fabric separately:

- Cost of 9.75 meters of atlas fabric: 9.75 meters * 42.8 rubles/meter = 417.3 rubles. - Cost of 10.5 meters of silk fabric: 10.5 meters * (42.8 rubles/meter - 4.78 rubles/meter) = 10.5 meters * 38.02 rubles/meter = 399.21 rubles.

Now, let's calculate the total cost by adding the costs of both fabrics:

Total cost = Cost of atlas fabric + Cost of silk fabric = 417.3 rubles + 399.21 rubles = 816.51 rubles.

Is 900 Rubles Enough?

Based on the calculations, the total cost of purchasing 9.75 meters of atlas fabric and 10.5 meters of silk fabric is 816.51 rubles.

Since 900 rubles is more than the total cost, 900 rubles is enough to purchase 9.75 meters of atlas fabric and 10.5 meters of silk fabric.
