Final answer:
Kerry runs 3 miles every day except her birthday, totaling 1,092 miles each year since she runs for 364 days.
Step-by-step explanation:
The question asks how many miles Kerry runs each year if she runs 3 miles every day except on her birthday. To calculate this, we need to know the number of days in a year and subtract one for her birthday. There are usually 365 days in a year, so excluding her birthday, Kerry runs 3 miles on 364 days.
To find the total number of miles Kerry runs in a year, we multiply the 3 miles she runs daily by the 364 days she runs each year:
3 miles/day × 364 days/year = 1,092 miles/year.
Therefore, Kerry runs 1,092 miles each year if she runs every day except her birthday.
