<u>Answer:</u>

The grade you make on your exam varies directly with the number of correct answers. The constant of variation is 5

<u>Solution:</u>

Given, The grade you make on your exam varies directly with the number of correct answers you get on the exam.

Answering 15 questions correctly will give you a grade of 75 what is the.

We have to find what is the Constant of variation.

Now, according to the given information, grade  number of correct answer

Then, grade = c x number of correct answers, where c is constant of variation.

Now, substitute grade = 75 and number of correct answers = 15

$\text { Then, } 75=c \times 15 \rightarrow c=\frac{75}{15}=5$

Hence, the constant of variation is 5
