I think Ms.Gonzalez got 217 prizes on Wednesday.All you had to do was divide 1,307 by 6.
The two answers are 23 and 47. You would subtract 24 from 70 then divide by 2 which would equal 23 then add the 24 back to it which is 47. 23 plus 47 equals 70.
So you just take 100% - 29% = 71%
So 71% of the students did not wear jeans
