Chrissie wants to go on a holiday. She has
135 hours leave available to use. Chrissie needs to keep 3 days available to go to a wedding in 2 months. If Chrissie works 7.5 hours a day, 5 days a week, how many weeks can she go on holidays for?

3 weeks

Step-by-step explanation:

She has 135 hours. A work day is 7.5. The three days for the wedding would use 7.5 * 3 hours or 22.5. 135 - 22.5 equals 112.5. To find out how many days, divide 112.5 by 7.5 to get 15. Then, because she works 5 days a week, divide 15 by 5 to get your answer of 3 weeks.
