Answer with explanation:</h2>
Let x denotes the number of days and y denotes the total change in gas price ( in dollars).
 Given : During the past seven days the price of regular gas is decreased by $0.2 each day.
Rate of decrease =$0.2 per day
Then , Total change in gas price = Rate of decrease x Number of days
i.e.
i.e. 
         (1)
To find the total change in gas price in 7 days , we put x= 7 in (1) , we get
 
    
Hence, the total change in gas price in 7 days = $1.4
 
        
             
        
        
        
D.  He will have $2,121.80.
After one year at 3% interst, $2000 becomes $2000 x 1.03 = $2,060.
During the second year, that $2060 x 1.03 becomes $2121.80
