Answer:
$179.18 ; Second class ticket
Step-by-step explanation:
The first step you want to do is set up the problem.
3rd) 50.99
2nd) 50.99-12.39= x
1st) 2(x+50.99)= y
From there, you subtract 50.99-12.39, which will give you 38.60. That is the cost of the 2nd class ticket.
Plug in the numbers into the final formula:
2(38.60+50.99)= 179.18.
That is the answer for the first question.
This leaves you with the third class ticket costing, $50.99, the second class ticket costing $38.60, and the first class ticket costing $179.18. The better option is the second class ticket.
