Answer: x=7.2

Step-by-step explanation:

Use the Pythagorean theorem:a^2+b^2=c^2 c being the hypothenuse and b and a being the other 2 sides

so 7.8*7.8=60.84 3*3+9 60.84-9=51.84 then the square of that would be 7.2 so x=7.2

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.
