A single train ticket costs $3.50. A book of 5 costs $15.00. How much can be saved by buying a book of 5 tickets rather than 5 single tickets? * $0.50 $5.00 $2.50 $1.50

$2.50

Step-by-step explanation:

All we need to do to solve this is find out how much 5 regular tickets will cost.

We know they cost 3.50 each so:

5 x 3.50 = 17.50

Now all we do is subtract the 15.00 the book would cost to find the "remainder" AKA what you save.

17.50 - 15.00 = 2.50

$2.50 is your answer.

Hope this helps and have a nice day!
