Given:
After learning how to fly, Wendy reduced her daily commute time by 75% Previously, her commute took m minutes.
To find:
Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly?
Solution:
Previously, Wendy commute took = m minutes.
After learning how to fly, Wendy reduced her daily commute time by 75%
Wendy's commute time, in minutes, after she learned how to fly
= m - 75% of m
= m - 75/100 × m
= m ( 1 - 75/100)
= m (25 / 100)
= m (1 / 4)
= m/4 minutes
Therefore, the new commuting time for Wendy is m/4 minutes
