Answer:
The doubling time of this investment would be 9.9 years.
Step-by-step explanation:
The appropriate equation for this compound interest is 
A = Pe^(rt), where P is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
If P doubles, then A = 2P
Thus, 2P = Pe^(0.07t)
Dividing both sides by P results in 2 = e^(0.07t)
Take the natural log of both sides:  ln 2 = 0.07t.
Then t = elapsed time = ln 2
                                        --------- = 0.69315/0.07 = 9.9
                                          0.07
The doubling time of this investment would be 9.9 years.
 
        
             
        
        
        
Answer:
21.5 Miles or 21 ½ Miles
Step-by-step explanation:
Plug in 7 as m to 3m + ½.
Then, I get 3(7) + ½.
That concludes to 21 + ½
Add the ".5" or "½" at the end 
So, answer is you get is 21.5 of 21 ½
