Can you help me with this?????????? (10 points!)

Ok, my friends and I are playing a math game. We give each other equations. If we get it right we get ten dollars. My friend gave me this equation:

Mr. Havel bought a car for $2400 and sold it for $2700. What percent of profit for Mr. Havel in selling the car?

Ok, I don't get it! Can you help me? I want that TEN DOLLARS!

12.5%

Lol! Sounds like a fun game.
Okay, to figure this out, you subtract the amount he sold it for from the amount he bought it.
$2700-$2400= $300
Then you divide $300 by $2400.
300/2400= .125
Push the decimal 2 to the right.
.125 to 12.5
The man made about a 12.5% profit.

I hope you get the 10 dollars!

Sales price: $2,700. Cost: $2,400

Profit, therefore, is $300

Percentage profit is generally expressed as a percentage of sales price, so:

$300/$2,700 = 1/9
1/9 = 0.11111111
0.11111111 = 11.111111%

He sold it $300 higher [2700-2400]

The percentage of profit = (300/2400)*100 = %12.5

If r is the increase, this is the equation to find out.
2400(1+r)=2700
2400+2400r=2700
2400r=300
r=.125
r=12.5%

the difference is $300 right? so he made $300 from spending $2400 so $300/$2400 = .125 then * 100 = 12.5%
