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.
, 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.

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


Therefore, we will save $167.2 with refurbished computer when we put the difference into the savings account for a year.
No the answer would be 3272.3 which is not a whole number
Answer:
True
Step-by-step explanation:
We can plug in and see.
If (3,0) is on the graph of P, then P(3) will evaluate to 0.
Let's try it:
P(3)=(3)^3-7(3)^2+15(3)-9
P(3)=27-7(9)+45-9
P(3)=27-63+45-9
P(3)=-36+45-9
P(3)=9-9
P(3)=0
Since P(3)=0, then (3,0) is an ordered pair of P.
