Answer:

11.5

Step-by-step explanation:

Simple interest formula:

I=P\cdot r\cdot t,

where

I = interest

P = principal

r = rate

t = time

In your case,

P = $4,000

I = $4,920 - $4,000 = $920

t = 2 years

So,

920=4,000\cdot r\cdot 2\\ \\r=\dfrac{920}{2\cdot 4,000}=0.115

The rate as decimal is 0.115 that is 11.5% as percent

Ian bought a discounted item for $50, if it was originally $75. What was the discount rate ? round to the nearest percent
kogti [31]

Answer:

Discount rate=33%

Step-by-step explanation:

Step 1

Determine the discounted amount as shown;

A=I-F

where;

A=discounted amount

I=initial price/original price

F=final price after discount

In our case;

A=unknown

I=$75

F=$50

replacing;

A=(75-50)=25

The discounted amount=$25

Step 2

Determine the discount rate using the formula;

Discount rate=(discount amount/original amount)×100

Discount rate=(25/75)×100=33.33%

Discount rate=33%

$5000 was invested into an account that earns an annual rate of 4.75%. If money is compounded monthly, how much will the account
Aleonysh [2.5K]

Answer:

  $5764.14

Step-by-step explanation:

The future value formula is useful here.

  FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

  FV = $5000(1 +.0475/12)^(12·3) = $5764.14

The account will be worth $5764.14 after 3 years.
