The total number of students in rolled at Berkmar middle school is 1400 students the ratio of boys to girls is 3 to 4 for the school how many students are boys and how many students are girls at Berkmar Middle school

Given:

Total number of students = 1400

The ratio of boys to girls is 3 to 4 for the school.

To find:

The number of boys and girls.

Solution:

We have,  Boy : Girls = 3:4.

Let number of boys be 3x and number of girls be 4x.

Total number of students = 1400

Divide both sides by 7.

Now,

Number of boys

Number of girls

Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
