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

Step-by-step explanation:GivenApproximate value = 20 friends

Exact Value = 24 friends

To determinePercent 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)
