The answer would be 2.45 acres. If you add 2.4 and 2.5, you get 4.9. If you divide 4.9 by 2, you get 2.45, which is how you determine what the halfway point is between two numbers.

Martha estimated there were 86 marbles in a jar for a contest. The actual number of marbles in the jar was 107. What was the
jekas [21]

Answer:

Roughly 20.4%

Step-by-step explanation:

Use the formula of percent of error:

| Actual number - Guess / Actual number | (100)

The actual number is 108 and the guessed number is 86:

| 108 - 86 / 108 | (100)

= | 22/108 | (100)

= | 0.2037037037 | (100)

The vertical lines indicate absolute value.  This means that anything inside of it must be turned into its positive form.  Since it is already positive, just take the signs away:

0.2037037037(100)

≈ 0.204(100)

= 20.4

Turn this into a percent:

20.4%

Martha's percent of error is 20.4%

Please tell me if I was right or not.  I really hope this helps!
