Answer:
34%
Step-by-step explanation:
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage increase.
1200/8 = x/3
150 = x/3
150 * 3 = x

Answer:
$900
Step-by-step explanation:
If the $810 is the price after 10% discount that means
$810 is 90% of the original price
So we divide 810 / 90% or 810 / 0.9
to get $900 as final price
Let's call the digits of the number ab a and b. Then the information in the question can be expressed as
a+b=12 => b=12-a
a*10+b + 54 = b*10+a => 9a + 54 = 9b
9a + 54 = 9(12-a) => 18a = 54 => a=3
b=12-a; b=9
39 swapped gives 93, 39+54=93
1000 + 450(36)
1000 + 16,200 = 17,200.
He payed $17,200 for the car.
Hope this helps!
