Answer 2

`\$\ 25`

Explanation:

By definition, the absolute error is defined as:

`\epsilon = |x_a - x_e|`

Where:

`\epsilon`: is the error

`x_a`: is the approximate value

`x_e`: is the exact value

In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

`\epsilon = |100 - 75|\\\epsilon = \$\ 25`
