One hiking club charges $20 to become a membr and $5 to participate on each hike. Another club charges no membership fee, but charges $7 to participate on each hike. How many bikes must you go on to make the first club more economical?
Can you show me step by step how to do this problem, and then give me the answer?...Thanks to whoever can help me!

OK Club A .$20+$5 per hike
Club B. $7. per hike.
After how many hikes does club B become more expensive?
I worked through my 5 and 7 times tables until the difference between them was greater than 20.
so 5 7
10 14
15 21
20 28
25 35
30 42
35 49
40 56
45 63
50 70
55 77
After 10 hikes you would have paid the same, after 11 you would have paid less.
There are probably quicker ways of doing this, but hope this helps.

That question makes no sense, are you sure you copied it down right?
