For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21

Answer:
The dimensions of each section will be 12.5 ft by 75 ft.
The area of each section will be 937.5 sq. ft.
Step-by-step explanation:
A parking lot with dimensions 50 ft. by 300 ft. is divided into sections by bisecting the width and the length.
So, each half will have dimensions 25 ft by 150 ft.
Each half is again bisected in length and width.
So, the dimensions of each section will be 12.5 ft by 75 ft.
Now, the area of each section will be (12.5 × 75) = 937.5 sq. ft. (Answer)
