    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
