A class of sixty voted for class presidents. 30% voted for brad and 70% voted for jane. how many votes votes did the winner get?

42 votes

Step-by-step explanation:

To do this we just need to set up an expression:  what 30 percent of 60 is.

This can be modeled by the expression: 0.3(60)

That equals 18

That means that 18 people voted for Brad.

Now we just have to subtract that from the total number of people to find who voted for Jane.

That can be modeled by: 60-18

which equals 42.

Since Jane won, the winner got 42 votes.
