Answer:
The number of hours did Tina work on Friday is "3.833 hours".
Step-by-step explanation:
Given,
Tina works 15 hours a week (Monday to Friday).
Last week she worked on,
Monday = 3 1/2 hours = 3.5 hours
Tuesday = 4 hours,
Wednesday = 2 1/6 hours = 2.167 hours,
Thursday = 1 1/2 hours = 1.5 hours.
∴ Number of hours did she work on Friday
= Tina works 15 hours a week (Monday to Friday) - Tinna last week she worked(Monday to Friday)
= 15 hours - ( 3.5 + 4 + 2.167 + 1.5) hours
= 15 hours - 11.167 hours
= 3.833 hours
Hence, the number of hours did she work on Friday is 3.833 hours
