Answer B 
Why is because Box B is near the 8 and goes on while Box A only is near 8 and stops there
        
             
        
        
        
It is 121 x 10^12 so the answer is A.
        
             
        
        
        
I don't agree with his statement. The first part says that he was paid $9.20 for the first 40 hours so we multiply them (9.20 x 40) to get 368. Then it says that he was paid 1.5 times that rate for every hour after that. The rate is "$9.20 per hour" so you find 1.5 times $9.20. You multiply $9.20 by 1.5 to get $13.80 per hour. Now you have to find how much money he got after the initial 40 hours. It says he worked 42.25 hours, and we already figured out how much money he got the first 40 hours ($368). So for the remaining 2.25 hours, Mr.Evens is paid $13.80 an hour. So we multiply 2.25 by $13.80 to get $31.05. To find out the total amount of money accumulated, we add. $368 + $31.05 is $399.05 which means that Mr.Evens is not correct. Hope this helped :]
        
                    
             
        
        
        
In this case were going to solve the question using "simple interst", so since were looking for the interest it will be I= PxRxT (I stands for "interest", P stands for "principal", R stands for "rate" and T stands for "time")
so P is $3000
R is 2%
and T is 3 years 
so we'll have to turn our rate into a decimal which is 2% = .02
now to start the problem:
I= (3000)(.02)(3)       (means 3000 x .02 x 3)
I= $180  is your answer
