Answer:

Step-by-step explanation:
use y = mx + b
slope(m) =
y-intercept(b) = 3
so,

-15m -30 = -12m +6
3m = 36
m= 36/3 =12
Add all the numbers together to find the total amount of college students surveyed.
355 + 292 + 280 + 191 + 198 + 136 + 66 + 24 = 1,542
The number is already simplified considering it's a whole number. The answer is either 1,542 or 1,500
<em>(I say either because when it says to simplify I'm not sure if they want it to be rounded.)</em>
