Answer:
t ≥ working hours for ticket sellers per week ÷ average ticket seller work hours per week
Explanation:
* Lets explain how to solve the problem
- Sapphire Island is open 7 days a week
- It has 8 ticket booths
- Each booth has a ticket seller from 10:00 am to 5 pm
- On average, ticket sellers work 30 hours per week
* Lets change these information to equation to find the minimum
number of ticket sellers t
∵ The time for each booth is from 10:00 am to 5:00 pm
∴ We need a ticket seller for 7 hours every day for each booth
∵ There are 8 booth
∴ The number of hours per day = 7 × 8 = 56 hours
∵ The Sapphire Island is open 7 days a week
∴ The number of hours per week = 56 × 7 = 392 hours
∵ The average ticket seller work hours is 30 hours per week
∵ The number of working hours for ticket sellers is 392 hours
per week
∵ t is the minimum number of ticket sellers
∴ t = 392/30 = 13.067
∴ The minimum number of ticket sellers is 14
∴ t ≥ working hours for ticket sellers per week ÷ average ticket seller
work hours per week
