Answer:
1988920000000000
Step-by-step explanation:
1.98892 x 1000000000000000 (15 zeros) 
The upper number (in this case 15) indicates the amount of zeros after the 1 (10 is 10^1, 100 is 10^2)
 
        
             
        
        
        
Total amount = Pe^(rt)
where 
P=principal
e=2.7182818284...
r=0.035
t=3 (years)
Total amount 
= 7565(e^(0.035*3)
=$ 8402.53
