Fast-Food Delight is open
from 6:00 A. M. to 10:30
P. M. on weekdays, 6:00
A. M. to 11:00 P. M. on
Saturdays, and 7:00
A. M. to 11:00 A. M. on
Sundays. How many
hours per week is Fast-
Food Delight open?

10.30p.m - 6.00a.m = 4.30

11.00p.m - 6.00a.m = 5.00

11.00p.m - 7.00a.m = 4.00

4.30 + 5.00 + 4.00 = 13.30

or you could do

4.30 + 4.00 = 8.30

8.30 + 5.00 = 13.30

13.30 = 1.30

I don't know if this is right, but i tried my best to help.
