A company did a survey to compare the popularity of two web browsers. It was found that 75 students used browser A and 40 of those students used browser B also. There were 18 students who did not use browser A but used browser B. There were 7 students who did not use either browser A or browser B.

Using a two-way table, predict the number of students who would use browser B when 300 students participate in the survey.
115
133
162
174
Can someone just tell is I did this right! My answer 174.
40+18=58 then 58*300/100=174 ?
