    Answer:Percent of the teachers surveyed had neither high blood pressure nor heart trouble = 24.99%

    Step-by-step explanation:

    We are given the following in the question:

    Number of teachers surveyed = 120

    Number of teachers had high blood pressure = 70

    Percentage of teachers had high blood pressure =

    Number of teachers had  heart trouble = 40

    Percentage of teachers had heart trouble =

    Number of teachers had both high blood pressure and heart trouble = 20

    Percentage of teachers had both high blood pressure and heart trouble =

    Percent of the teachers surveyed had high blood pressure or heart trouble = Percent of teachers had high blood pressure +Percent of teachers had  heart trouble – Percent of teachers had both high blood pressure and heart trouble

    Percent of the teachers surveyed had neither high blood pressure nor heart trouble

    = 100% – Percent of the teachers surveyed had high blood pressure or heart trouble
