Calculation of the Price of a Tulip and a Narcissus

To calculate the price of a tulip and a narcissus, let's assign variables to represent their prices. Let's say the price of one tulip is x rubles, and the price of one narcissus is y rubles.

According to the given information, a bouquet of two tulips and one narcissus costs 40 rubles. Additionally, it is mentioned that one tulip is twice as expensive as one narcissus.

Based on this information, we can set up the following equation:

2x + y = 40

Since one tulip is twice as expensive as one narcissus, we can also write:

x = 2y

Now we can solve this system of equations to find the values of x and y.

Substituting the value of x from the second equation into the first equation, we get:

2(2y) + y = 40

Simplifying the equation:

4y + y = 40

Combining like terms:

5y = 40

Dividing both sides by 5:

y = 8

Now that we have the value of y, we can substitute it back into the second equation to find the value of x:

x = 2(8) = 16

Therefore, the price of one tulip is 16 rubles and the price of one narcissus is 8 rubles.

Please note that the search results did not provide specific information to verify this calculation. However, the calculation is based on the given information and the assumption that the prices of the flowers are represented by variables.
