Problem Analysis

The problem states that a cake with cream roses was cut into pieces in such a way that each piece had one rose. There were a total of three straight cuts made from one edge of the cake to the other. The question is how many roses could be on the cake.

Solution

To solve this problem, we need to determine the maximum number of roses that could be on the cake after making three straight cuts.

Let's consider the possible scenarios:

1. If the cake was cut into four pieces, each with one rose, then there could be a maximum of 4 roses on the cake. 2. If the cake was cut into five pieces, each with one rose, then there could be a maximum of 5 roses on the cake. 3. If the cake was cut into six pieces, each with one rose, then there could be a maximum of 6 roses on the cake. 4. If the cake was cut into seven pieces, each with one rose, then there could be a maximum of 7 roses on the cake. 5. If the cake was cut into eight pieces, each with one rose, then there could be a maximum of 8 roses on the cake. 6. If the cake was cut into nine pieces, each with one rose, then there could be a maximum of 9 roses on the cake. 7. If the cake was cut into ten pieces, each with one rose, then there could be a maximum of 10 roses on the cake. 8. If the cake was cut into eleven pieces, each with one rose, then there could be a maximum of 11 roses on the cake. 9. If the cake was cut into twelve pieces, each with one rose, then there could be a maximum of 12 roses on the cake.

Based on the above scenarios, the possible number of roses on the cake could be from 4 to 12. Therefore, the correct answer is A. from 4 to 7.

Conclusion

The cake could have had a minimum of 4 roses and a maximum of 7 roses on it.
