You estimate that there are 45 marbles in a jar. The actual amount is 82 marbles. Find the percent error. Round to the nearest tenth of a percent.

45.1

Step-by-step explanation:

The original amount is 82

But the wrong amount is 45

So we will have to calculate the percentage for the error

82-45

37

So %error = 37/82 * 100

=3700/82

=45.121~45.1 (to nearest tenth)

So the final answer is 45.1%
