Answer 1

the total cost includng the sales tax is $648

Explanation:

Hello, I can hel p you with this,.

to solve this you can use a rule of three

Step 1

let

the price of the video game is $60, is tis our 100%

$60 ⇔100%

the tax is 8%,

so the total price is=price of the game + tax

total price=100%+8 %

total price= 108%

Step 2

define the relation

let x as the total cost

$60 ⇔100%

X ⇔ 108%

`\alpha (60)/(100) =(x)/(108) \\isolate\ x\\(60*108)/(100) =x \\\\x=(6480)/(10)\\ x=648`

so, the total cost is $648

have a nice day
