Question

20. Business and finance. Paul invested $5000 in a time deposit. What interest will
he earn for 1 year if the interest rate is 6.5%?

Answer 1

i think 5000*.065=325 [thats the interest he gets for 1 yr]

Answer 2

I think if you take 5000 and multiply it by 1.065 you will get the answer, then take the 5000 from it and there you go.

Another way to do it is to figure out what 6.5% of 5000 is, so you work out 1% first by dividing 5000 by 100 = 50. 50 is 1% of 5000. Now just multipl 50 by 6.5 to make the amount of interest added after a year.

Answer 3

5000 * 6.5% = 325

Answer 4

Assuming simple interest, 0.065*5000

Answer 5

For this problem you need this formula: A = Pe^rt

A is what you are trying to find

P is the invesment (5000)

e is a constant (e = 2.27, kinda like pie)

r is rate

t is time

A = 5000e^(0.065)(1)
A = 5000e^(0.065)

After this you have to plug in e to the 0.065 to your calculator.
Then multiply it by 5000.

Answer 6

y=5000(1.065)^x
y=5000(1.065)^1
y=5325

5325-5000=325
