Answer: 280
First, add together all the visitors on each day to get the total visitors from Monday to Friday.
75+150+100+200+175=700
There were 700 visitors in total on the weekdays, but only 2/5 of that total on the weekends. This can be calculated by dividing 700 by 5 and then multiplying the answer by 2.
700/5=140
140*2=280
Alternatively, you can multiply 700 by 2/5.
700*2/5=280
