Question 560240
Let x = number of bus fares.


Cost of fares without coupon book = 1.50x
Cost of fares WITH coupon book = .50x + 21


1.50x = .50x+21


To solve the equation, subtract .50x from each side of the equation:
1.50x -.50x = .50x-.50x + 21
1.00x = 21
x= 21 fares


Solving Word Problems is not nearly as hard as most people think they are.  For a non-traditional explanation, please see my own website.  To find my website, use the easy-to-remember and easy-to-spell website www.mathinlivingcolor.com.  Then click on the link at the bottom of this page to take you to my Homepage.


Near the top of my Homepage, look for the link called "Basic, Intermediate, and College Algebra: One Step at a Time."  Choose the "Basic Algebra" link, and look in "Chapter 1" for "Sections 1.09 and 1.10" on Word Problems.  You will really like the "MATH IN LIVING COLOR" sections that go with these sections, where many of the hardest problems are solved for you in COLOR.


I have explanations on most topics from algebra that might be easier for you to understand than your own textbook.  The entire website is FREE!!  If anyone needs help finding a page on my website, send me an Email at rapaljer@seminolestate.edu.
