Answer:
Total after 11 years: $46,010.25
Just interest after 11 years: $3,110.25
Step-by-step explanation:
Multiply 3900 by 0.0725, which is the decimal version of 7.25%
3900×0.0725=282.75
Add that interest (which is interest for one year) to the 3900. You get 4182.75. That is one year of the principle and interest combined.
Multiply this by 11.
11×4182.75= 46,010.25
If you need to find just the amount of interest over 11 years, multiply the 282.75, which we found earlier, by 11.
282.75×11=3110.25
