how many girls are there

girls drink 4 cups e/a of water 7 cups are consume by the boys e/a and coach drinks 9 cups of water with a total of 43 cups consume how many girls are in the team

To find the number of girls on the team, we can start by subtracting the water consumed by the boys and the coach from the total cups consumed.

Let x be the number of girls on the team.

Girls drink 4 cups each, so the total cups consumed by the girls would be 4x.

Boys drink 7 cups each, and there are x boys, so the total cups consumed by the boys would be 7x.

The coach drinks 9 cups, so the total cups consumed by the coach would be 9.

The total cups consumed by everyone would be 4x + 7x + 9.

We know that the total cups consumed is 43, so we can set up the equation:

4x + 7x + 9 = 43.

Simplifying this equation, we have:

11x + 9 = 43.

Subtracting 9 from both sides, we get:

11x = 34.

Dividing both sides by 11, we find:

x = 3.

Therefore, there are 3 girls on the team.
