Answer:

Concept: Mathematical Representation

  1. You have a two digit # __
  2. The sum of the two digit # = 13
  3. The original # increased by 9
  4. Hence we must find values that sum to 13. *Note they must be independently standing.
  5. 8+5, 9+6, 7+6 , 6+7 , and etc
  6. The value must also increase by 9
  7. So logically it would be any result that when switched that value would be 76-67= 9.
  8. So the value must be 67

The price of a car has been reduced from $15,000 to $9,000. What is the percentage decrease of the price of the car?
Fynjy0 [20]

Answer:

40<em>% is the decrease.</em>

<em />

Step-by-step explanation:

<em>To figure out the percentage decrease, you would first subtract the two numbers. </em>

<em />

<em />15000 - 9000 = 6000<em />

<em />

<em>Next, you would divide that number by the total.</em>

<em />

<em />6000 / 15000 = .4<em />

<em />

<em />15000 * .4 = 6000<em />

<em />

<em />15000 - 6000 = 9000<em />

<em />

<em />40<em>% </em><em>would be the decrease percentage. </em>
