The use of the conjunction "or" for "Friday or Saturday" means that you have to include the reservations for both days.
The graph has these values:
Mon: 5
Tue: 3
Wed: 4
Thu: 7
Fri: 26
Sat: 30
Sun: 9
The total number of reservations for the week is 5+3+4+7+26+30+9 = 84
The number of reservation for Friday and Saturday is: 26+30 = 56
The percent is (56/84)*100 =
Now simplify: (8*7)(4*25) / (4*21) % = 1400/21 %
To convert to mix number divide 1400 / 21 and use the whole part of the quotiend plus the residue divided by the dividend, which is 66+ 14/21.
So the mixed number is 66 and 14/21 %
Answer: 66 and 14/21 %
