Answer:

Rate of interest will be 1.33 %

Return on this investment = =\frac{9020-9000}{9000}=0.222 %

Step-by-step explanation:

We have given principle amount P = $9000

Time = 61 days = \frac{61}{365}=0.167\ years

We have to find the rate of interest

Total amount produce at the end of term = $9020

So interest = $9020 - $9000 = $20

We know that simple interest =\frac{principle\ amount\times rate\times\ time}{100}

20=\frac{9000\times rate\times\\ 0.167}{100}

rate=1.33 %

Return on this investment = =\frac{9020-9000}{9000}=0.222 %

charle [14.2K]

Hello :D

$40.00 x 3 = $120.00

$20.00 x 2 = $40.00

$120.00 + $40.00 = $160.00

$400.00 - $160.00 = $240.00

There is $240.00 left in the account.
