Question

Help With Number 8 Please?

Answer 1

The answer is about 8.14 years :) 

Because,  ↓ 

Unit Rate =  $\frac{I}{1300 * 0.0425 }$  which is equal to → $\frac{450}{1300 * . 0425}$ 

and that's how I found out that my answer is 8.14 years 

Answer 2

I = p r t First subtract 1750-1300 to find out how much interest was earned. 450=1300(.0425)t ; solve by multiplying 1300*.0425 then divide 450 by that number. You get approx 8.14 years.
