The answer would be A) $79.20
 (220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9
 
        
             
        
        
        
Answer:
-0.25
Step-by-step explanation:
1-3= -2 
9-2= 8
-2/8= -0.25
 
        
             
        
        
        
22+24+26+28+30+32+34+36+38+40+42+44= 396
        
                    
             
        
        
        
That's two questions.
The answer to the second question is:  Yes.
The answer to the first question is:
Multiply 60 miles per hour by ' 1 ' a few times.  Use fractions that have 
the same thing on top and bottom, since those are always equal to ' 1 '.
Then cancel units if the same unit is on the top and the bottom.
Here's how it goes: 
(60 mi/hr) x (5280 ft/mile) x (1hr/3600 sec) = (60 x 5280 / 3600) ft/sec = <u>88 ft/sec</u>
