To determine which city has a higher unit rate of rainfall based on rainy days, we can compare the annual totals.
- Phoenix, Arizona has 33 rainy days per year.
- Jacksonville, Florida has 10 rainy days per month. Over a year (12 months), this amounts to: \[ 10 \text{ rainy days/month} \times 12 \text{ months/year} = 120 \text{ rainy days/year}. \]
Now, comparing the two:
- Phoenix: 33 rainy days/year
- Jacksonville: 120 rainy days/year
Thus, Jacksonville, Florida has a higher unit rate of rainfall because it experiences more rainy days annually (120 days) compared to Phoenix (33 days).
So the correct conclusion is: Jacksonville, because Jacksonville has 120 rainy days per year and Phoenix has only 33 rainy days per year.
