Problem Analysis

We are given the following information: - 2 notebooks cost the same as 1 notebook. - 1 set of paints is 4 times more expensive than 1 notebook. - We need to determine if 100 rubles is enough to buy 8 notebooks, 2 notebooks, and 1 set of paints.

Solution

Let's break down the problem step by step:

1. Determine the cost of 1 notebook. - We are given that 2 notebooks cost the same as 1 notebook. - Therefore, the cost of 1 notebook is half the cost of 2 notebooks. - Let's calculate the cost of 1 notebook: 2 notebooks = 1 notebook.

2. Determine the cost of 1 set of paints. - We are given that 1 set of paints is 4 times more expensive than 1 notebook. - Therefore, the cost of 1 set of paints is 4 times the cost of 1 notebook. - Let's calculate the cost of 1 set of paints: 1 set of paints = 4 notebooks.

3. Calculate the total cost of 8 notebooks, 2 notebooks, and 1 set of paints. - We need to determine if 100 rubles is enough to buy these items. - Let's calculate the total cost: - Cost of 8 notebooks = 8 * (cost of 1 notebook) - Cost of 2 notebooks = 2 * (cost of 1 notebook) - Cost of 1 set of paints = (cost of 1 set of paints) - Let's substitute the values we calculated earlier: - Cost of 8 notebooks = 8 * (2 notebooks) - Cost of 2 notebooks = 2 * (2 notebooks) - Cost of 1 set of paints = (4 notebooks)

4. Compare the total cost with 100 rubles. - If the total cost is less than or equal to 100 rubles, then we can buy the items with 100 rubles. - If the total cost is greater than 100 rubles, then we cannot buy the items with 100 rubles.

Let's calculate the total cost and determine if 100 rubles is enough to buy the items.

Calculation

1. Cost of 1 notebook = 2 notebooks = 4 rubles. 2. Cost of 1 set of paints = 4 notebooks = 16 rubles. 3. Total cost: - Cost of 8 notebooks = 8 * (2 notebooks) = 8 * 4 rubles = 32 rubles. - Cost of 2 notebooks = 2 * (2 notebooks) = 2 * 4 rubles = 8 rubles. - Cost of 1 set of paints = 16 rubles. - Total cost = Cost of 8 notebooks + Cost of 2 notebooks + Cost of 1 set of paints = 32 rubles + 8 rubles + 16 rubles = 56 rubles.

Conclusion

The total cost of 8 notebooks, 2 notebooks, and 1 set of paints is 56 rubles. Since 100 rubles is greater than 56 rubles, 100 rubles is enough to buy 8 such notebooks, 2 notebooks, and 1 set of paints.
