You can
put this solution on YOUR website!One hiking club charges $20 to become a memeber and $5 to participate on each hike. Another club charges no membership fee,but charges $7 to participate on each hike. How many hikes must you go on to make the first club more economical?
--------------
Let "x" be the number of hikes.
-------------
1st club expenses:
C(x) = 20 + 5x
2nd club expenses:
C(x) = 7x
--------------
INEQUALITY:
20+5x<7x
20 < 2x
x > 10 hikes
------------
If there are more than 10 hikes the 1st club is less expensive,
