Question

Ron is taking an inventory at his store. Based on previous sales, he predicted sales of 25 folders and 230 erasers. He actually sold 30 folders and 200 erasers. What is the percent error for the erasers?

Answer 1

Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%

Answer 2

Answer: There is 15% error for the erasers

Step-by-step explanation:

Since we have given that

Number of folders he predicted = 25

Number of erasers he predicted = 230

Total number of inventories he predicted is given by

$230+25=255$

Number of erasers he actually sold = 200

Number of folders he actually sold = 30

Total number of inventories he actually sold is given by

$200+30=230$

Error in estimation is given by

$230-200=30$

Percentage of error for the erasers only  

$\frac{30}{200}\times 100\\\\=\frac{30}{2}\\\\=15\%$

Hence, there is 15% error for the erasers.
