Lauren predicts she will take 129 photos during vacation. If Lauren actually takes 111 photos, what is Lauren's percent error? Round your answer to the nearest tenth.

Lauren's percent error = 13.95% Approx

Step-by-step explanation:

Given:

Number of photos predict = 129

Number of photos actual = 111

Find:

Lauren's percent error

Computation:

Lauren's percent error = [(Number of photos predict - Number of photos actual)/(Number of photos predict)]100

Lauren's percent error = [(129 - 111)/129]100

Lauren's percent error = [(129 - 111)/129]100

Lauren's percent error = [(18)/129]100

Lauren's percent error = 13.95% Approx
