Heather wants to buy a new car but needs money for the down payment. her parents agree to lend her money at an annual rate of2% , charged as simple interest. they lend her $3000 for 3years. she makes no payments except the one at the end of that time.

Respuesta :

The Simple interest paid is $180, and the total repayment amount that must be paid is $3180.

It follows that:

$3,000 for the principal.

Interest rate, R = 2%

T = 3 years for time 

(a) Interest paid in full:

The formula for simple interest is as follows:

SI = P * T* R /100

Using P, R, and T quantities to calculate simple interest

SI = PTR/100

SI = 3000 * 3 *2 /100

SI = $180

(b) Total repayment amount: 

(b) Total repayment amount: 

Amount equals Principal plus Simple Interest

Amount = Principal + Simple Interest

Amount = 3000 + 180 = $3180

So, Total repayment amount = $3180

Therefore, the simple interest paid  and the total repayment amount which should be paid is $180 and $3180 respectively.
