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) 0.25m(B) 0.75m(C) 1.75m(D) 41m(E) 43m
Understand Percentage Reduction: Understand the percentage reduction in Wendy's commute time. Wendy reduced her daily commute time by 75%. This means she now only spends 25% of her original commute time traveling.
Convert to Decimal: Convert the percentage to a decimal to find the factor by which Wendy's commute time is reduced. 75% reduction means Wendy is using 100%−75%=25% of her original commute time. To convert this percentage to a decimal, we divide by 100: 10025=0.25
Apply Decimal Factor: Apply the decimal factor to Wendy's original commute time to find the new commute time.If Wendy's original commute time is m minutes, then her new commute time after learning to fly is 0.25m.
Identify Correct Expressions: Identify the correct expressions from the given options that represent Wendy's new commute time.The expression 0.25m is equivalent to 41m, so options A and D are correct. The other options do not represent a 75% reduction in time.
