Calculate Daily to Yearly: Converting 5 Cups × 365 Days

To solve this problem, we will calculate the total number of cups Mariano drinks in a year:

• Step 1: Identify the number of cups Mariano drinks per day, which is given as 5 cups.

• Step 2: Identify the number of days in a year, generally considered to be 365 days.

• Step 3: Multiply the daily consumption by the number of days in a year: $5 \times 365$.

Performing the calculation:
$5 \times 365 = 1825$.

Therefore, Mariano drinks a total of 1825 cups of tea in a year. This corresponds to choice number 2: \text{ \( 1825 } \).
