Question

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

Answer 1

25%

Explanation:

Use formula

`\text{Percent increase}=\frac{\text{New price - Old price}}{\text{Old price}}\cdot 100\%`

Old price = $800

New value = $1,000

Hence, the percent increase is

`(1,000-800)/(800)\cdot 100\%=(200)/(800)\cdot 100\%=(1)/(4)\cdot 100\%=25\%`
