Question

A laptop computer was marked up 100% from an original cost of $740. Last Friday, Judy bought the laptop computer and paid an additional 10% in sales tax. What was her total cost?

Answer 1

Answer:

$1628

Step-by-step explanation:

A laptop computer was marked up 100% from an original cost of $740.

Marked up price = 100% of $740

= $740

Current price of the Laptop = Initial price of the Laptop + Marked up price

= $740 + $740

= $1480

Last Friday, Judy bought the laptop computer and paid an additional 10% in sales tax. What was her total cost?

Sales tax = 10% of the cost of laptop

= 10% × $1480

Sales tax = $148

Judy's total cost = Price of the Laptop + Sales tax

= $1480 + $148

= $1628
