A principle of $20,000 is invested at $6.25 and earns $10,000 simple interest how many years has the money been invested
slava [35]

Answer:

The money was invested for 8 years.

Step-by-step explanation:

Given that a principal of $ 20,000 is invested at 6.25% and earns $ 10,000 simple interest, to determine how many years has the money been invested, the following calculation has to be performed:

(20,000 x 0.0625) x X = 10,000

1,250X = 10,000

X = 10,000 / 1,250

X = 8

Thus, the money was invested for 8 years.

Sally is 10 years older than one fifth of her mother’s age. If Sally is 20 years old, how old is her mother?
slamgirl [31]

S = Sally

M = Mother

S = M/5 + 10

20 = M/5 + 10

20 - 10 = M/5

10 = M/5

M = 10 * 5

M = 50

----------------

Her mother is 50 yo

-----------------

50 : 5 + 10 = 20
