Answer 3

Problem Analysis

We are given that a bouquet of roses is three times more expensive than a bouquet of carnations. Additionally, the cost of the rose bouquet is 50 rubles more than the cost of the carnation bouquet. We need to determine how many bouquets of roses can be purchased for 70 rubles.

Solution

Let's assume the cost of the carnation bouquet is x rubles. According to the given information, the cost of the rose bouquet is three times the cost of the carnation bouquet, so it would be 3x rubles. Additionally, the cost of the rose bouquet is 50 rubles more than the cost of the carnation bouquet, so we can write the equation:

3x = x + 50

Simplifying the equation, we have:

2x = 50

Solving for x, we find:

x = 25

Therefore, the cost of the carnation bouquet is 25 rubles, and the cost of the rose bouquet is 3 * 25 = 75 rubles.

To determine how many bouquets of roses can be purchased for 70 rubles, we divide 70 by the cost of one rose bouquet:

Number of bouquets of roses = 70 / 75 = 0.9333

Since we cannot purchase a fraction of a bouquet, we can conclude that it is not possible to buy any bouquets of roses for 70 rubles.

Answer

It is not possible to buy any bouquets of roses for 70 rubles.
