Question

Vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from Hartford to Denver was$200. Now the cost is $330. What is the percent increase? What would be the percent increase if theairline charges an additional $50 baggage fee with the new ticket price?The percent increase of the airline ticket is .%.(Round to the nearest percent as needed.)

Answer 1

The percent increase is given by:

`\text{ \%increase=}\frac{\text{ Final value - Starting value }}{\text{Starting value}}*100`

a. The starting value is $200.

The final value is $330.

The percent increase is then:

`\begin{gathered} \text{ \%increase = }(330-200)/(200)*100=(130)/(200)*100 \\ \text{\%increase = }65\text{ \%} \end{gathered}`

b. Now, if the airline charges an additional $50 baggage fee to the new ticket, the new final value is: $330 + $50= $380.

Then the percent increase is:

`\begin{gathered} \text{\%increase = }(380-200)/(200)*100=(180)/(200)*100 \\ \text{\%increase = }90\text{ \%} \end{gathered}`
