A teacher invested $600 in an account that paid 2% annual simple
interest. The teacher did not make any additional deposits or
withdrawals.
What is the total amount of interest paid by this investment at the end of
3 years?
$12.00
$36.00
$360.00
$120.00

$36.00

Step-by-step explanation:

The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3year(s) time periods. So t is 3year time periods.To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),  or 600.00 + 36.00 = 636.00.

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
