First you need to turn this into an improper fraction. Then, using your improper fraction, you simplify
        
                    
             
        
        
        
Well let's see what floor each one lands on and figure out which one is higher.
Something to note:
down = subtracting
up = adding
if something says it's doing something more than once, add it the number of times it's doing that thing. (You can also multiply it by that number but the adding way is a bit easier to understand and explain)
<u>Elevator 1:</u>
6 + 7 + 7 - 10 = 10
<u>Elevator 2:</u>
20 - 5 - 5 - 5 + 12 = 17
Elevator 2 ends on a higher floor (reasoning above)

Answer:
-30
Step-by-step explanation:
 In g(8) the 8 = n.  So, substitute 8 in for n in the expression -4n + 2
g(8)  =  -4(8) + 2 = -32 + 2 = -30
