Approximate Value Exact Value Error Absolute Error Ratio Percent Error
$100
$75
$25
How much was the absolute error in his estimate?
$
Intro

Answer 1

Absolute error = $25

Explanation:

Given that:

Amount spent by John on shopping trip = $75

Estimated amount to spent on shopping trip = $100

Absolute error = Approximate value - Exact value

Here,

Approximate value = $100

Exact value = $75

Absolute error = 100 - 75

Absolute error = $25

Percentage =
`(Absolute\ error)/(Exact\ value)*100`

Percentage =
`(25)/(75)*100`

Percentage = 33.33%

Hence,

Absolute error = $25
