To find the percentage of how many reservations of of Friday or Saturday compared to the total reservation , we just need sum all the reservations of the week , 15 + 5 + 10 + 25 + 40 + 30 + 35 = 160 160 = 100% Now we just need to divide the amount of reservations on Friday or Saturday by 160
Friday : 40 ÷ 160 = 1/4 = 0.25 Which is 25%
Saturday: 30÷ 160 = 0.1875 Which is 18.75%
Awnser : Friday compose 25% of all reservations and Saturday 18.75%
