Answer 3

Solution:

Let's solve the problem step by step.

1. Number of Daisies and Violets: - Let's denote the number of daisies as D and the number of violets as V. - According to the given information, each bouquet contains 15 daisies and 10 violets, and the total number of flowers is 125. - We can set up the following equation to represent this information: 15D + 10V = 125.

2. Number of Girls and Boys in First Grade: - Let's denote the number of girls as G and the number of boys as B. - The total number of children in the first grade is 75, with 13 girls and 12 boys in each class. - We can set up the following equation to represent this information: 13G + 12B = 75.

Calculation:

1. Number of Daisies and Violets: - Using the given equation 15D + 10V = 125, we can solve for the number of daisies and violets. - By solving this equation, we find that there are 5 daisies and 10 violets.

2. Number of Girls and Boys in First Grade: - Using the given equation 13G + 12B = 75, we can solve for the number of girls and boys. - By solving this equation, we find that there are 5 girls and 6 boys.

Conclusion:

So, the girl made a total of 5 daisies and 10 violets. In the first grade, there are 5 girls and 6 boys.
