Answer: B

Step-by-step explanation:

y=x+6

y=-2x-3

x+6=-2x-3

Add 2x to both sides

3x+6=-3

Subtract 6 from both sides

3x=-9

Divide 3 from both sides

x=-3

Put into equations

y=-3+6

y=3

A furniture store pays a wholesale price for a mattress.
WITCHER [35]

Answer:

Step-by-step explanation:

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.

Therefore, the wholesale price, before the markup was $960
