Question

a college professor teaches a class of 80 students. fourteen students are business majors, six are education majors, and the rest are undecided. what percentage of the class is undecided?

Answer 1

Total students: 80

We know that:

-business has 14 students

-education has 6 students

-undecided has x students

We need to find out x! So we can add 14 and 6 up and subtract it by 80 to figure out the amount of undecided students there are.

80-(14+6)=60

To find out the percentage, we divide the number of undecided students by the number of total students, and multiply it by 100.

60/80=30/40=0.75=0.75*100=75%

75% of the class is undecided for a major
