Answer 1

697 (option C)

Explanation:

From 100 students:

Number of students tha t work to school = 82

Number that don't walk to school = 18

If there are 850 students:

let the number of those who work to school = y

82 who walk = 100 total

y who walk = 850 total

cross multiply:

82(850) = y(100)

69700 = 100y

100y/100 = 69700 /100

y = 697

The principal should expect 697 students will walk to school (option C)
