Calculating the Cost of Chrysanthemums and Lilies

To calculate the cost of chrysanthemums and lilies, we can use the given information that a bouquet of two chrysanthemums and one lily costs 66 rubles, and the lily is 9 rubles cheaper than the chrysanthemum.

Let's denote the cost of the chrysanthemum as C and the cost of the lily as L.

Given: - 2C + L = 66 (the cost of the bouquet) - L = C - 9 (the lily is 9 rubles cheaper than the chrysanthemum)

We can use these equations to find the individual costs.

First, let's express L in terms of C using the second equation: L = C - 9

Now, substitute L = C - 9 into the first equation: 2C + (C - 9) = 66 3C - 9 = 66 3C = 75 C = 25

Now that we have the cost of the chrysanthemum, we can find the cost of the lily using L = C - 9: L = 25 - 9 L = 16

Conclusion

The cost of the chrysanthemum is 25 rubles, and the cost of the lily is 16 rubles.
