Answer explanation

Choice D is correct. There are 60 minutes in one hour, so an 8-hour workday has 60 times 8, equals 480 minutes. To calculate 15% of 480, multiply 0.15 by 480: 0 point 1 5 times 480, equals 72. Therefore, Lani spent 72 minutes of her workday in meetings.

Choice A is incorrect because 1.2 is 15% of 8, which gives the time Lani spent of her workday in meetings in hours, not minutes. Choices B and C are incorrect and may be the result of computation errors.
