Answer:
r<4
Step-by-step explanation: 
-3(r-4)>0 step 1: distribute the -3
-3r+12>0  explain: -3 times r =-3r, -3 times -4 = 12
next, isolate the -3r by putting 12 on the other side
-3r+12>0    subtract 12 from both sides
-3r>-12    now, divide both sides by -3    (you have to flip the > because you are dividing by a negative) -12 divided by -3 is 4
so you should end up with r<4
 
        
             
        
        
        
First, do 100-14 to find out how much percent doesn't get the coupon= 85
then find 85% of 64= 54.4
finally, your answer is: 54.4
        
             
        
        
        
32% * 25 =
(32*25)/100
800/100=8
8%
        
             
        
        
        
1.1x=17.85
x=16.227272727272727...
Round to $16.23
        
                    
             
        
        
        
To find the answer you need to find the square root of e^2 to get e so what you do to one side of the equation you do to the other side of the equation so find the square root of 0.36.
e=positive or negative 0.6
