The correct answer is 21.5 days
Explanation:
We know Marissa has two paid days of vacation plus 1 day for every four months she works. In this context, the first step is to find how much paid days of vacation she will have for working 6.5 years and add this to the 2 paid days of vacation she was given when she began to work. The steps are shown below:
1. Find the number of months in 6.5 by considering each year has 12 months and half year (0.5) is equivalent to 6 months
6 (number of years) x 12 months = 72 months
0.5 year = 6 months
72 months + 6 months = 78 months (Total of months in 6.5 years)
2. Divide the total of months into 4 considering every 4 months Marissa is given one paid day of vacation.
78 months ÷ 4 = 19.5 days (number of paid days of vacation for working 6.5 years)
Finally, add this result to the two paid days initially given 19.5 days + 2 days = 21.5 days
