Betty -Difference quotient:==The next step isn't hard, but is time-consuming.  What you need to do is multiply this all out and then simply. I'll leave it for you to do the mathThe LAST step is to plug in r=0.07The final answer you should get is 1000(1.07)=1070Hope that helps

use a calculator cause i dont even know wat the problem is
