Mrs. Ming invested an amount of money in two accounts for one year. She invested some at 8% interest and the rest at 6% interest
dimaraw [331]

Interest rate for one year is rate percent amount of original investment. The amount invested by Mrs. Ming in the account paying 6% was $680

<h3>How to calculate interest after 1 year if the rate of interest is R% annually?</h3>

Suppose that annually there is interest rate of R%. The amount initially invested is P, then for 1 year, it doesn't matter if its simple or compounding annually, the interest is same (it doesn't remain same if compounding isn't annually or if the time is > 1 year)

The interest for 1 year will be \dfrac{P}{100} \times R

Let we have the initial amount spent in account paying 8% interest rate as $x

Let for 6% interest paying account, initial amount was $y

Then, by the given data, we have:

x + y = 1500

and

\dfrac{x}{100} \times 8 + \dfrac{y}{100} \times 6=  106.40\\\\8x + 6y = 10640\\4x + 3y = 5320

Thus, we got a system of linear equations as :

x + y = 1500\\4x + 3y = 5320

From equation 1, getting value of x in terms of y, we get:

x = 1500 - y

Substituting this value in second equation, we get:

4x + 3y = 5320\\4(1500-y) +3y = 5320\\6000 - y = 5320\\y =680

Putting this value of y in the equation we got for x,

x = 1500 - y\\x = 1500 - 680= 820

Thus, amount invested by Mrs Ming in account paying 8% interest rate as $x = $820

and  for 6% interest paying account, initial amount was $y = $680

Thus,

The amount invested by Mrs. Ming in the account paying 6% was $680
