Question

Katrin estimated that she sold 40 sandwiches at her food truck during lunch. Later, a count showed that she actually sold 44. Find Katrin's percent error to the nearest tenth.

Answer 1

10%

Explanation:

percent error: p

44 - 40 = 4

4/40 × 100 = p

p = 0.1 × 100

p = 10%

Percent error is 10%
