The principal observes 8th grade the following day. Of the 120 students, 42 brought their lunch from home, 72 purchased lunches,
and 6 brought a lunch from home and purchased an ice cream. Explain how the principal could use the numbers from 7th grade to predict the 8th grade possibilities.
by finding each chart such as if there are 120 7th graders and 180 8th graders he can use the same numbers from the 7th graders and compare each percentage to the 8th-grade kids and get a close enough answer
