Final answer:
Ricardo gets approximately 41.94% of the time in the vacation home by choosing the first time slot, from July 1 to July 13, out of the total 31 days in July.
Step-by-step explanation:
The divide and choose method is a way to evenly divide resources or time between two parties. In this scenario, David, as the divider, splits the days of July into two periods. The first period runs from July 1 to July 13 and the second from July 14 to July 31.
Since Ricardo chooses the first time slot, we calculate his percent of the time by determining how many days he gets and dividing it by the total number of days in July.
Ricardo’s time spans 13 days. July has 31 days. To find the percentage of time Ricardo gets, we carry out the calculation (13 days / 31 days) × 100.
(13/31) x 100 = 41.94%
This equals approximately 41.94%. So, Ricardo gets about 41.94% of the time in the vacation home for the month of July.
