You can multiply 16 times what equls 88 and then divide by 4 much more simple than it sounds and also your in high school and u cant solve this problem
Answer:
6
Step-by-step explanation:
total no. of seats = 22 x 4 = 88
total no. of seats occupied = 19 * 4 + (22-19)*4/2 = 76 + 6 = 82
no. of empty seats = 88 -82 = 6
25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
