Question

Букет из двух хризантем и одной лилии стоит 66 руб.,причём лилия на 9 руб. дешевле хризантемы.Какова цена лилии и цена хризантемы?

Answer 1

Х-цена хризантемы, тогда х-9 - цена лилии, составляю уравнение:
2x+x-9=66
3x=66+9=75
X=75/3=25
Значит, 25 рублей-цена хризантемы, тогда 25-9=16 рублей- цена лилии

Answer 2

Пусть х цена хризантемы, тогда
2*х + (х-9) = 66
3*х = 66+9
3*х=75
х=25 руб стоит хризантема
25-9 = 16 руб стоит лилия

Answer 3

Calculation of the Prices of the Lily and Chrysanthemum

To determine the prices of the lily and chrysanthemum, we can use the given information that a bouquet consisting of two chrysanthemums and one lily costs 66 rubles, with the lily being 9 rubles cheaper than the chrysanthemum.

Let's assume the price of the chrysanthemum is x rubles. According to the given information, the price of the lily would then be (x - 9) rubles.

To calculate the total cost of the bouquet, we can add the prices of the two chrysanthemums and the lily:

2x + (x - 9) = 66

Simplifying the equation:

3x - 9 = 66

Adding 9 to both sides:

3x = 75

Dividing both sides by 3:

x = 25

Therefore, the price of the chrysanthemum is 25 rubles, and the price of the lily is (25 - 9) = 16 rubles.

So, the price of the lily is 16 rubles, and the price of the chrysanthemum is 25 rubles.

Please note that the above calculation is based on the given information and assumes that the prices of the flowers are in rubles.
