Answer: The computer Lea wants to buy is listed at a regular price of $400.00.
During the sale, the computer will be discounted by 30%. So, the price after the discount will be:
$400.00 - (30% of $400.00) = $400.00 - $120.00 = $280.00
If Lea buys the computer before 9:00 a.m. on that same Saturday, she will get an additional 10% discount. So, the price after both discounts will be:
$280.00 - (10% of $280.00) = $280.00 - $28.00 = $252.00
Therefore, Lea will pay $252.00, without tax, when she buys the computer that Saturday before 9:00 a.m.
