Harry is planning a trip by air. He has to choose the cheaper of two airlines. Airline A charges $50 for a ticket and $25 per bag of luggage. Airline B charges $30 for a ticket and $30 per bag of luggage. Harry determines that, given his number of suitcases, the two airlines are equivalent in terms of cost. How much will it cost? How many suitcases did he have?

Harry has 4 suitcases and it will costs $150!

Step-by-step explanation:

First we have to put the terms we know into an equation.

Airline A : $50 + $25x = t

Airline B : $30 + $30x = t

Now, we can input numbers into our variables in a table.

                      Airline A                                          Airline B

1                  50 + 25(1) = 65                              30 + 30(1) = 60

2                50 + 25(2) = 100                            30 + 30(2) = 90

3                 50 + 25(3) = 125                             30 + 30(3) = 120

4                 50 + 25(4) = 150                             30 + 30(4) = 150

So, from this info we know that Harry has 4 suitcases and it will costs $150!

Hope this Helps! :)
