Answer:

n_A = 283

n_C =198

n_{A \cup C}=429

n_{A \cap C}= 52

And we want to find the number of students that are taking Algebra but not Calculus.

We can solve this problem with the figure attached.

So we want to find this number of elements P represent number of elements:

P(A \cap C')

And we can find this number of elements with this formula:

P(A \cap C')= P(A) -P(A \cap C) = 283-52= 231

And that represent the number of students that are taking Algebra but not Calculus.

Step-by-step explanation:

For this case we define the following notation:

A = represent the students taking College Algebra

C =  represent the students taking College Calculus

A U C= represent the students taking College algerba or Calculus

A \cap B represent the students taking College and Calculus

From the information given we have this:

n_A = 283

n_C =198

n_{A \cup C}=429

n_{A \cap C}= 52

And we want to find the number of students that are taking Algebra but not Calculus.

We can solve this problem with the figure attached.

So we want to find this number of elements P represent number of elements:

P(A \cap C')

And we can find this number of elements with this formula:

P(A \cap C')= P(A) -P(A \cap C) = 283-52= 231

And that represent the number of students that are taking Algebra but not Calculus.
