Question

Airplane ticket prices for a concert increased from $800.00 to $1000.00. What was the percent of the increase?

Answer 1

Answer:

25%

Step-by-step explanation:

Use formula

$\text{Percent increase}=\dfrac{\text{New price - Old price}}{\text{Old price}}\cdot 100\%$

Old price = $800

New value = $1,000

Hence, the percent increase is

$\dfrac{1,000-800}{800}\cdot 100\%=\dfrac{200}{800}\cdot 100\%=\dfrac{1}{4}\cdot 100\%=25\%$
