The bar graph shows the numbers of reserved campsites at a campground for one week. what percent of the reservations were for friday or saturday? write the percent as a mixed number in simplest form.

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 %

66 and 14/21 %

The answer is 225 miles per 4.5 hours. hope this ; )
