Q. After learning how to fly, Wendy reduced her daily commute time by 75%. Previously, her commute took m minutes.Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly?Choose 2 answers:A 0.75mB 43mC 1.75mD 0.25mE 41m
Understand percentage reduction: Understand the percentage reduction.Wendy reduced her daily commute time by 75%. This means she now only spends 25% of her original commute time, because 100%−75%=25%.
Convert percentage to decimal: Convert the percentage to a decimal.To find the equivalent decimal for 25%, divide 25 by 100, which gives 0.25.
Apply decimal to commute time: Apply the decimal to Wendy's original commute time.If Wendy's original commute time is m minutes, then her new commute time after the reduction is 0.25×m.
Convert percentage to fraction: Convert the percentage to a fraction.Another way to express 25% as a fraction is 10025, which simplifies to 41.
Apply fraction to commute time: Apply the fraction to Wendy's original commute time. Wendy's new commute time can also be represented as (41)m.
Identify correct answer choices: Identify the correct answer choices.From the given options, 0.25m (Option D) and (1/4)m (Option E) both represent 25% of Wendy's original commute time, which is the correct reduction.
