Answer:
percent change = 25% (drop)
Step-by-step explanation:
James reasoning is incorrect
Let the original price of the computer = $1000
If the computer was marked up by 50% then 1000 x 1.5 = $1500
If the computer was then marked down by 50% then 1500 x 0.5 = $750
Percent change = [ (difference between final value and initial value) ÷ initial value] x 100
= [ (1000 - 750) ÷ 1000 ] x 100
= 25% (drop)
2000 Pounds in a ton. 1.5 is 1 and a half. 2000/2 = 1000. 2000 + 1000 = 3000. 1.5 tons = 3k pounds. You reduce the weight of the car by 300 pounds. 3000 - 300 = 2700.
Your car weighs 2,700 pounds.
2,700 pounds is also equal to 1.35 tons
30x + 30y = 450
20x + 25y = 345
answer: 3 square ft per minute
Answer:
x = 3
Step-by-step explanation:
First set up the problem like this:
14x-17 = 8x + 1
Now we subtract 14x from each side. This leaves us with:
-17 = 6x+1
Now we need subtract 1 from each side, leaving us with:
-18 = -6x
And now we divide each side by 6x, leaving us with.
3 = x.
And if you insert three into both of the equations, it will result in 25.
(Hope this helped!)
