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}
