143.7 I believe since you take 6.80*20=136+46=2.3*20
136+46=182
182*7.65%=168.08
168.08*8.95%=153.04
153.04*6.1%=143.7
I believe it's a 25% profit.
950+250= 1200
1500-1200= 300
300/1200= 0.25
0.25 x 100= 25%
Answer:
12
Step-by-step explanation:
If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?
25 * 3 = 75
87 - 75 = 12
