52%
Explanation
Step 1
let
original cost=$250
new cost=330
to find the percentage of increasing
[tex]\begin{gathered} \frac{new\text{ price}}{\text{original price}}\cdot100=\frac{330}{250}\cdot100=1.32 \\ \\ 1.32\Rightarrow132\text{ per cent} \end{gathered}[/tex]it means the increase is 32%
Step 2
What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price.
the new price is= 330+50
new price(fee included)=380
and do the same:
[tex]\frac{new\text{ price}}{\text{original price}}\cdot100=\frac{380}{250}\cdot100=1.52\cdot100=152[/tex]the new price is 152% of the original, it measn the increase is
52%
