Answer:

21 students were in the class.

Step-by-step explanation:

The information in the question tells you that 4/7 of the class is girls.

That means that the remainder of the class is 1 - 4/7 = 3/7 boys

Let the total in the class = x

(3/7)x = 9           Multiply by 7

(3/7)*7*x = 9 * 7 Simplify the right and left

3x = 63              Divide by 3

3x/3 = 63/3

x = 21

There were 21 students in the class.

Based on the given description above, here is how we are going to solve it.
Let n be the number of years. So the equation will be like this.
37000n + 1500n = 1025000
Now let us solve for n.
38500n = 1025000 <<<divide by sides by 38500 and the result is
n=26.62
Therefore, it will take 26 years and 6 months before you made a total salary of 1,025,000 dollars. Hope that this answer helps.
