Answer:

The percent error based on the average measurements is 0.8%.

Step-by-step explanation:

The standard equation for percent error is [(original - actual)/original} x 100.  The original amount is 100 degrees celcius.  Your average measurement can be found by adding the three temperatures together and dividing by the number of temperatures collected:  98.5 + 99.3 + 99.8 = 297.63/3 = 99.2.  When we place our numbers into the equation and solve, we get:  (100 - 99.2)/100 = 0.008 x 100 (to get our percentage) = 0.8%.
