PLEASE HELP ME

Lea wants to save money on a new computer. At the store near her, the computer she wants is listed at a regular price of 400.00.

•On Saturday, the store will have a sale and discount the computer by 30%.

•Shoppers who buy a computer that same Saturday before 9:00 am will also receive an additional 10% off the already discounted price.

how much will lea pay, without tax, when she buys the computer that Saturday before 9:00 a. m?

(a) $148.00

(b) $160.00

(c) $240.00

(d) $252.00

D) 252.00

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

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

y -5 = (-1/4)(x + 8)
