You are debating about whether to buy a new computer for $800.00 or a refurbished computer with the same equipment for $640.00.
Misha Larkins [42]

Answer:

$167.2

Step-by-step explanation:

It has been given that the price of a new computer is $800.00 and refurbished computer with the same equipment has a  price of $640.00.

Let us find the amount that we will save with a refurbished computer if we put the difference into the savings account for a year using simple interest formula.  

A=P(1+rt), where A= Amount after t years, P=principal amount, r = interest rate (decimal form) and t=time.

Our principal amount will be the difference of prices of new computer and refurbished computer.

\text{Principal amount}=800-640=160

\text{Interest rate}=\frac{4.5}{100}=0.045  

Upon substituting our given values in above formula we will get,

\text{Amount we will save with a refurbished computer}=160(1+0.045\times 1)

\text{Amount we will save with a refurbished computer}=160(1+0.045)  

\text{Amount we will save with a refurbished computer}=160(1.045)

\text{Amount we will save with a refurbished computer}=167.2

Therefore, we will save $167.2 with refurbished computer when we put the difference into the savings account for a year.
