Answer:
The percentage decrease is 27%
Step-by-step explanation:
To find the percent decrease, first find the difference in the two costs. 
$205,000 - $149,650 = $55,350
Now divide that number by the original cost. 
$55,350/$205,000 = 27%
 
        
             
        
        
        
Step-by-step explanation:

→ 77x = 126
→ x = 126 ÷ 77
→ x = 1.63
 
        
             
        
        
        
It would be 31+t.
