Answer:
Step-by-step explanation:
Given:
Hairstylist schedule:
1/4 hour to trim a customer's hair
1/6 hour to style the customer's hair
Work per week:
2 × 1/3 hours per day
= 7/3 hours oer day
5 days a week
Hours in a week = 7/3 × 5
= 35/3 hours per week.
A customer must have hair styled and trimmed.
Total number of hours per customer = 1/4 + 1/6
= 5/12 hours per customer.
Therefore, 28 appointments can be nade each week.
Total number of hours per week = 5/12 × number of customers, n
35/3 = 5/12 n
n = 28 customers per week
