A group of friends are planning a road trip. If they all contributed $24, then they would be $6 short of the total. If they all contributed $25, then they would have $3 more than needed. What is the total cost of the trip?

Question

anonymous · Answer

So that's $24 each? or $25 each right?

anonymous · Answer

Yeah

anonymous · Answer

So, let f = number of friends in group. 

Then we know that this is true right?

24f + 6 = 25f-3

anonymous · Answer

Wait Wait Slow down trying to solve for f

anonymous · Answer

Ohh I see

anonymous · Answer

So what did you get for f?

anonymous · Answer

9but wouldn't it be -6 and +3 how?

anonymous · Answer

So you know that f = 9, then just sub into one of two equations:
Either C = 24f+6 or C = 25f - 3
