They have a scale factor of 5:6 so first we need to find the perimeter of KLM:

Then apply the scale factor of 5:6:

Set the denominators equal:

So we see that the perimeter of GHJ is 35.
The raised price represents 110% of the original price (100% plus the extra 10%)
A percentage is converted into a decimal multiplier by dividing by 100:

To clarify the final stage, consider this (where

is the original price):


From here, basic algebraic rules make solving for

easy:

Therefore the original price of a ticket was $175
