Lets figure out how many students total in Lorenzo's grade:
7 students + 21 students = <u>28 total students</u>
<u />
We know that we can find the percentage by dividing our value by the total amount and multiplying it by , which is 1. (Multiplying by 1 does not change anything, which is why we choose to do this.)
Taking our known values,
<em>Therefore, </em><em>25%</em><em> of students voted for the athlete.</em>
The rate of growth of the functio y=3x is 3. The rate of growth of the second function is 3 too. Therefore, the rate of growth of both functions is the same.
