answer choices: a. 148 b. 160 c. 240 d. 252

D. $252

Step-by-step explanation:

Initial price of computer = $400

Less 30 % = -0.30 × 400 = - 120

                       Sale price =   280

Less 10 % = -0.10 × 280 =     -28

                     Final price =  $252

If Lea buys her computer on Saturday before 9 pm, she will pay $252.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
