Final answer:
It rained on 30% of the past 60 days, which calculates to 18 days of rain. The closest available option to this number is 20 days (Option A).
Step-by-step explanation:
The meteorologist said that it rained during 30% of the past 60 days. To find the number of days it rained, you multiply the total number of days by the percentage of days with rain. Doing the math:
60 days * 30% = 60 * 0.30 = 18 days.
Therefore, the number of days it rained is closer to option A, which is 20 days, than it is to any of the other options.
