Shirley invested a total of $12,000 in two certificates of deposit. One pays 6% interest, and the other pays 7% interest. Her total interest at the end of one year is $790. How much is invested in the CD that pays 6% interest?

Question

anonymous · Answer

Let x represent the amount to earn an interest of 6%. Then the amount to earn an interest of 7% will be 12000-x.
The expression showing the total interest shall therefore be
6%*x+7%(12000-x)=790. Will you solve for x then? That will give you the value you require
