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

Answer :

Final answer:

Chrissie can use 112.5 hours of her leave to go on holiday after keeping 22.5 hours for the wedding. Given her weekly working hours of 37.5 hours, she can go on holiday for 3 weeks.

Explanation:

Firstly, let's calculate how many hours Chrissie needs to set aside for the wedding. She works 7.5 hours a day, if she needs 3 days, this equals 7.5 * 3 = 22.5 hours.

Once we subtract this from her total leave hours, she has 135 - 22.5 = 112.5 hours left for her holiday.

Knowing that a full working week for Chrissie is 7.5 hours/day * 5 days = 37.5 hours/week, we can calculate how many full weeks she can take off by dividing her holiday hours by her working hours per week: 112.5 / 37.5 = 3 weeks. Therefore, Chrissie can go on a holiday for 3 weeks.

Answer:

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.
