What percentage increase occurs in the price of a round-trip economy plane ticket from New York to London by electing to go during the peak season as opposed to going on the regular economy class?

16.2

19.4

84.8

119.4

19.4%

Step-by-step explanation:

So, each price is describing how much will be paid for a round trip. The question specifically asks about "electing to go during the peak season as opposed to going on the regular economy class" So those are the two we want to look for. Specifically the economy options.

From the table, regular economy is 440.80 while peak season economy is 526.30. The question is asking what is the percent increase to get from the regular one to the peak season one.

In other words we solve for x in the equation 440.8 (1 + x) = 526.3 where x will get us the decimal form of the percent. Then just multiply by 100.

So some quick algebra tells us x =.194 or 19.4%

You can check this. Start with 440.8 and multiply by 1.194
