The students at Mill Middle School held a class election. Alyssa and Megan were the only two
candidates running for class president. Megan
received 21 votes and Alyssa received 29 votes.
What percent of the votes did Alyssa receive?

Total no.of votes = 21+29=50

No. of votes Megan received = 20

No.of votes Alyssa received = 29

Let x% be the percentage of votes Alyssa received.

Which means :

Therefore, Alyssa received 58% of the total votes.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
