Question

Mr. Candelaria estimates that the drama

club sold 400 tickets to the school play. The drama club actually sold 462 tickets. Calculate Mr. Candelaria's percent error.

Answer 1

To calculate percent error, you can use the formula:

percent error = (|experimental value - theoretical value| / theoretical value) x 100%

In this case, the experimental value is the actual number of tickets sold (462), and the theoretical value is the estimate made by Mr. Candelaria (400). Plugging these values into the formula:

percent error = (|462 - 400| / 400) x 100%

percent error = (62 / 400) x 100%

percent error = 0.155 x 100%

percent error = 15.5%

So, Mr. Candelaria's percent error is 15.5%. This means that his estimate was off by 15.5% of the actual number of tickets sold.
