a) 5525
b) 84,600
c) 10,152
d) 3525

Answer 1

D) 3,525

Explanation:

To find how many students are in the entire college you need to set up a proportion.

So there are 24 international students out 200 students, so this will be your first ratio. 24/200

Since we need to how many students are in the entire college we will put 423 over x. 423/x

So now you have 24/200 = 423/x

Now you have to do Cross Product Property

So multiply 200 by 423, which is 84,600

Then 24*x = 24x

So 24x = 84,600

Now divide 24 by itself and then by 84,600

24/24 = 1

84,600/24 = 3525

So x = 3525, There are 3,525 students in the entire college
