The price of an item yesterday was $60. Today, the price fell to $42. Find the percentage decrease.

Respuesta :

Answer:

-30% or 30% decrease

Step-by-step explanation:

What's percentage decrease?

  • Percent decrease is the difference between the initial value and new value, indicating a loss of value.
  • The formula to find percent decrease is [tex]\frac{NV-IV}{IV} * 100[/tex], where NV = new value and IV = initial value.

How do we solve this problem?

  • We know that the original value was $60, so that represents IV. Also, now that the price is $42, it represents NV.
  • Now, we plug in the values!
  • [tex]\frac{42-60}{60} * 100[/tex]
  • [tex]\frac{-18}{60} * 100[/tex]
  • [tex]-\frac{3}{10} * 100[/tex]
  • [tex]-3 * 10[/tex]
  • [tex]-30[/tex]

Therefore, the answer is 30% decrease.
