Answer:

Step-by-step explanation:

A. Calculating The Markdown Price

X=Markdown price

Original price: $600

Markdown rate: 20%

100%-20%=80%

The TV's price is now 80% of what it originally was.

$\frac{x}{600} =\frac{80}{100\\}$

100x=48000

x=480

The price of the TV after being marked down is $480.

B. Calculating The Sales Tax

Y=Total sales tax

TV price: $480

Sales tax: 10% or 0.1

y=480*0.1

y=48

The total sales tax is $48

C. Calculating Your Total

x+y=total

480+48=total

total=528

You in total pay $528 for the TV.
