Answer:
70%
Step-by-step explanation:
Out of all the 12th grade students there are 27 who are looking at 2 colleges and 23 looking at 3+.
First you need to add the 27 looking at 2 colleges and the 23 looking at 3+.
27+23 = 50
Now you take the total 12th grade students (170) and subtract it by the total number of 12th grade students looking at 2 and 3+ colleges (50) and put that all over the total.
[tex]\frac{170-50}{170}[/tex] -> [tex]\frac{120}{170}[/tex]
Then you solve which would be
0.70 or 70%
