Answer:1084
Step-by-step explanation:you take 126 x 9 and if the teachers are free you leave them out and you get ten dollars for every 25 students and 5 x 25 is 125 that means you take your answer from 126 x 9 and subtract 50 and it leaves you with 1084
19/25 * 100 = 1900/25 = 76 ....numbers greater then 15
7/50 * 100 = 700/50 = 14....numbers less then 15
100 - (76 + 14) = 100 - 90 = 10 <== numbers equal to 15
