    Answer:

    Her percent error was: ≈ 17% (whole percent)

    Step-by-step explanation:

    Given

    Approximate value = 20 friends

    Exact Value = 24 friends

    To determine

    Percent error

    Using the formula to calculate the Percent error

    Percent error = | Approximate Value| – Exact Value | / | Exact value | × 100

                           = | 20 – 24 | / | 24 | × 100

                           = | – 4 | / | 24 | × 100

    Apply absolute value: |-a| = a,   a>0

                           = 4/24 × 100

                           = 16.67 %

                           ≈ 17% (whole percent)

    Thus, her percent error was: ≈ 17% (whole percent)
