There were 28 students inside a bus before stopping at an intersection. After stopping at an intersection, there were 58 students on the bus. What's 40% of the number of students who entered the bus at the intermediate stop?
At the intermediate stop, 58-28=<<58-28=30>>30 students entered the bus before it stopped at the intersection.
40% of the number of students who entered the bus at the intermediate stop is 40/100*30=<<40/100*30=12>>12
