Answer 1

Answer:

Tyler has two savings accounts that his grandparents opened for him. One of the accounts pay 7% annual interest, whereas the other pays 9% annual interest. If you have $700 more invested at 9% than you invested at 7%, how much do you have invested in each account if the total amount of interest you earn in a year is $127?

***

let x=amount invested in 7% account

700+x=amount invested in 9% account

..

7%x+9%(700+x)=127

.07x+63+.09x=127

.16x=64

x=400

700+x=1100

amount invested in 7% account=$400

amount invested in 9% account=$1100
