A small college has 1250 students. There are 30 more women than men. How many women attend the college?

Solving using arithmetic mentally:

If there are as many men as women, then there would be 1250/2=625 each.
If 30 more women than men attend the college, you would "take out" 15 men and replace them with women to make 625+15=640 women.

Using algebra:
Let w=number of women
number of men = 1250-w
If women outnumber men by 30 then
w-(1250-w) = 30
2w = 1250+30
2w = 1280
w = 640
There are 640 women on campus.

Well, first we need to determine how many men attend the college. Let's assume there are M men. Since there are 30 more women than men, the number of women would be M + 30.

Now, the total number of students in the college is 1250, so we can write the equation: M + (M + 30) = 1250.

Simplifying this equation, we get: 2M + 30 = 1250.

Subtracting 30 from both sides, we get: 2M = 1220.

Now, we can divide both sides by 2: M = 610.

So, there are 610 men attending the college.

To find the number of women, we substitute the value of M back into the equation: M + 30 = 610 + 30 = 640.

Therefore, there are 640 women attending the college.

Let's solve this step-by-step.

Let's represent the number of men as 'x'.

Given that there are 30 more women than men, the number of women can be represented as 'x + 30'.

Now, we know that the total number of students is 1250.

So, the equation can be formed as:

x + (x + 30) = 1250

Simplifying the equation:

2x + 30 = 1250

Subtracting 30 from both sides:

2x = 1220

Dividing both sides by 2:

x = 1220/2
x = 610

So, there are 610 men in the college.

Substituting this value in the equation for the number of women:

x + 30 = 610 + 30
x + 30 = 640

Therefore, there are 640 women attending the college.

To find out the number of women attending the college, we can set up a system of equations based on the given information. Let's suppose the number of men is "m" and the number of women is "w."

Given that there are 30 more women than men, we have the equation:
w = m + 30

We also know that the total number of students is 1250, so we can create another equation:
m + w = 1250

Now, we can substitute the value of "w" from the first equation into the second equation and solve for "m":

m + (m + 30) = 1250
2m + 30 = 1250
2m = 1250 - 30
2m = 1220
m = 1220 / 2
m = 610

Now we know that there are 610 men attending the college. To find the number of women, we substitute this value of "m" back into the equation we created earlier:

w = 610 + 30
w = 640

Therefore, there are 640 women attending the college.
