To determine the average number of pools sold each month over the six-month period, we need to follow a series of steps:
1. List the number of pools sold each month:
- February: 11
- March: 10
- April: 12
- May: 16
- June: 15
- July: 18
2. Calculate the total number of pools sold:
To find the total, sum the number of pools sold each month:
[tex]\[
11 + 10 + 12 + 16 + 15 + 18 = 82
\][/tex]
Thus, the total number of pools sold over the six months is 82 pools.
3. Determine the number of months:
There are six months (February, March, April, May, June, and July).
4. Calculate the average number of pools sold per month:
To find the average, divide the total number of pools sold by the number of months:
[tex]\[
\frac{82}{6} \approx 13.666666666666666
\][/tex]
5. Round the average to one decimal place:
The value [tex]\(13.666666666666666\)[/tex] rounds to 13.7 when rounded to one decimal place.
Therefore, the average number of pools sold each month over this six-month period is closest to:
d. 13.7 pools
