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

The percent error is 10%. Step-by-step explanation: To calculate percent error, we first subtract the measured value from the actual value. In this case, we have a measured value of 44 and an actual value of 40, so we get: p = (44 - 40) / 40 x 100 Simplifying this expression, we get: p = 4 / 40 x 100 p = 0.1 x 100 p = 10% Therefore, the percent error is 10%.
