Problem Analysis

In the garden, there are 8 red roses and 4 white roses. All the white roses and 3 red roses were cut for a bouquet. We need to determine how many roses are left in the garden and if it is possible to solve the problem with just one operation.

Solution

To find out how many roses are left in the garden, we need to subtract the number of roses that were cut for the bouquet from the total number of roses in the garden.

Total number of roses in the garden = 8 red roses + 4 white roses = 12 roses.

Number of roses cut for the bouquet = 3 red roses + 4 white roses = 7 roses.

Number of roses left in the garden = Total number of roses in the garden - Number of roses cut for the bouquet = 12 roses - 7 roses = 5 roses.

Therefore, there are 5 roses left in the garden.

Can the problem be solved with one operation?

No, the problem cannot be solved with just one operation. We need to perform two operations: cutting the white roses and cutting the 3 red roses.

Conclusion

In the garden, there are 5 roses left after cutting all the white roses and 3 red roses for a bouquet. The problem cannot be solved with just one operation; two operations are required.
