Answer 1

Step-by-step explanation:

Tina works 15 hours a week (Monday to Friday).

Last week she worked on,

Monday = 3 hours = 3.5 hours

Tuesday = 4 hours,

Wednesday = 2 hours = 2.167 hours,

Thursday = 1 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
