Problem Analysis

The problem states that the graduates of class 11 "A" are buying flower bouquets for the last bell ceremony. They plan to give each teacher 3 roses and the class teacher and the principal 7 roses each. They want to buy a total of 15 bouquets, including the class teacher and the principal. The roses are being purchased at a wholesale price of 35 rubles per piece. The task is to calculate the total cost of all the roses.

Solution

To calculate the total cost of the roses, we need to determine the number of roses required and multiply it by the price per rose.

Let's calculate the number of roses required for each teacher: - Each teacher will receive 3 roses. - There are 15 teachers in total, including the class teacher and the principal. - Therefore, the total number of roses required for the teachers is 3 * 15 = 45 roses.

The class teacher and the principal will receive 7 roses each, so the total number of roses required for them is 7 + 7 = 14 roses.

The total number of roses required is the sum of the roses for the teachers and the roses for the class teacher and the principal, which is 45 + 14 = 59 roses.

Now, let's calculate the total cost of the roses: - The roses are being purchased at a wholesale price of 35 rubles per piece. - Therefore, the total cost of the roses is 35 * 59 = 2065 rubles.

So, the total cost of all the roses is 2065 rubles.

Answer: The total cost of all the roses is 2065 rubles.
