Answer:
This is a binomial.
Step-by-step explanation:
Bi means two. Therefore, since this polynomial only has two integers it is a binomial.
 
        
             
        
        
        
500 people took the survey.
12 out of 15 people is 80% of the population.  12/15 = 0.80
Thus, 80% of the population prefers eating in the restaurant.
 
If 400 represents the people who prefers eating in the restaurant; then, 400 is the 80% of the population. To get the total population or 100%, we must divide 400 by 0.80 or 80%
400 / 0.80 = 500 people.
Out of the 500 people, 400 selected eating in the restaurant while the remaining 20% of the population or 100 people selected cooking at home.
        
                    
             
        
        
        
Each can of green beans costs  ($3.00/5) = 60¢  at the
village market, and  ($6.10/10) = 61¢  at Sam's Club.
If you're watching every penny, then that MIGHT be enough 
of a difference to make you decide to buy your beans at the
village market, but not necessarily.
If, say, the village market is farther away from you, or if there are 
other things you're going to get from Sam's anyway, then you 
should buy your beans there too.
        
             
        
        
        
(-35-42-63)/7= (-140)/7=-20
