Question

you bought two antique lamps for the $50 each. Later you offered $60 for one and sold it. When you saw a duplicate being sold for more you changed your mind and bought it back for $70. you then sold it for $80. the first one didn't sell at all so you reduced the price by 10% below what you originally paid and managed to get rid of it. did you make or lose money on the deal and how much ??

please include the steps you used thanks =]]

Answer 1

2 Lamps for $50 = $100

Sold one for $60. Then you buy it back for $70. Then you sell if for $80.

Then sell first one $50 less 10% (-5) = $45.

Total costs = 50 +50 +70 = $170
Total sales = 60+80+45 =$185

You made $15

Hope that helps.

Answer 2

I'm not a math guy; so, I DOUBT that I set this up the way a teacher would want you too. But I can get the right answer. It's pretty simple:

We're talking about two lamps and a final total. Chart their courses separately:

Lamp1 - Original purchase minus $50.
- Later sold it for $60, putting you up $10.
- Later bought it back for $70, putting minus $60.
- Finally sold it for $80, putting you ahead $20.

Lamp2 - Original purchas minus $50
- Finally sold it for 90 percent of your purchase price or
.9 * 50 = $45, setting you minus $5.

$20 - $5 = $15 profit

Answer 3

okay..
1. you are in the hole -$100 because each lamp cost $50.

2. you then sold one for $60, so you would take -100+60= -40.

3. then you bought it back for $70, so you would take -40-70= -110.

4. you then sold it for $80, so you would take -110+80= -40.

5. then you took the original price of the lamp ($50) and marked it 10% off, which would be 50 x .10= $5.

6. So, you would take 50-5= 45 (the marked down price).

7. then add 45 to -40 and you get the answer of $5.

So, yes you made $5 in the deal.

Answer 4

yes you lost on the deal. you actually lost $35.

Answer 5

wow! thats a lot of work. Good Luck!
