A) $148.00
B) $160.00
C) $240.00
D) $252.00

D) $252.00

Step-by-step explanation:

Regular Price = $400

Price at Saturday with 30% discount = (400/100) x 70 = $280

Price with additional 10% discount on discounted price = (280/100) x 90 = $252

B. $160.00

Step-by-step explanation:

Given the regular price of the computer as $400.00

Discount is 30% on a Saturday and addition 10% if you buy before 9am .

Lee buys before 9am , so his discount is 30% + 10%

= %40

Amount to be paid by Lee = 40% /100% x $400.00

0.4 x $400.00

$160.00

Lee will pay $160.00 if she buys the computer before 9am
