To start, first add up the total number of reservations made this week which would be adding up the total amount of reservations for each day:
15+5+10+25+40+30+35= 160
Then, since it is asking for the percent of Friday and Saturday, add the amounts together (40+30) which is 70.
Then, set these as a fraction where it is the reservations for Friday and Saturday over the total amount of reservations: 70/160
Now that you got that, do 70 divided by 160 which is 0.4375.
Finally, convert 0.4375 to a percent by moving the decimal right two and you get 43.75% as your answer.
