The science class is taking a field trip. there are a 20 students and a unknown number of adults. the bus holds 35 people at most. what is the greatest number of adults who can chaperone?

It would be 15 because the 35 people at most minus the 20 students equals 15 so that would be the greatest number of adults allowed to be there.

15 because 35 minus 20 equals 15.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
