Tyler has two savings accounts that his grandparents opened for him. one of the accounts pay 10 % 10% annual interest, whereas the other pays 11 % 11% annual interest. if you have $ 700 $700 more invested at 11 % 11% than you invested at 10 % 10%, how much do you have invested in each account if the total amount of interest you earn in a year is $ 161 $161?

at 10%  $  400

at 11%   $ 1,100

Explanation:

principal x rate x time = interest

there is an account which yields at 10%another at 11% which also, is $700 dollar greater.

both yield 161 dollars

the equation would be:

We can solve for the principal at 10%

Then first principal is for 400 dollars

the second: 400 + 700 = 1,100 dollars

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
