Question 118189This question is from textbook Fubd of Alg and Trig
: This is an application that falls under this category. I have worked it to the end but need a little guidance.
An airline that flies from LA to Albuquerque with a stopover in Phoenix charges a fare of $45 to Pheonix and a fare of $60 from LA to Albuq. A total of 185 passengers boarded the plane in LA and fares totaled $10,500. How many passengers got off of the plane in Pheonix?
This is how I sat the problem up:
x+y= 185
45x+60y= 10,500
I know this problem should be solved using elimination.
So I mult E1 by -45 in order to eliminate.
-45(x+y)= 185
-45x-45y= 185
45x+60y= 10,500
With this I end up with..
15y=10,685
then I divided by 15 but got a decimal...am I doing this right? This question is from textbook Fubd of Alg and Trig

you didn't multiply the WHOLE equation by -45 (what about the 185?)
