If Mitch wants to have 10 spare bars and he could only afford 28, how many candy bars his friends could have?

anonymous · Answer

18

zepp · Answer

Correct, now if you want to distribute equally the amount of candy among 'f' friend, how many candy bars will each friend get?

anonymous · Answer

9

zepp · Answer

We do not know how many friends he has, he has 'f' friends.

anonymous · Answer

but it says 2 to each friend so i did 18/2

zepp · Answer

Yes, 9 friends, but each friend would get 2 bars, correct?

zepp · Answer

But let's suppose we do not know and we do not want to solve the problem, we'll keep f as the number of friends, you agree that, 18/2 = f

anonymous · Answer

yes

zepp · Answer

So in words, the amount of candy bars Mitch wants to keep for himself, added to the amount of candy bars his friends would get, gives 28

zepp · Answer

Amount of candy bars Mitch wants to keep for himself is 10
Amount of candy bars his friend would get, in term of the variable 'f', would the the number of friend (f) times the number of candies each of them would receive, 2, thus, 2f

Therefore the equation to express this would be?

anonymous · Answer

so which equation 2f-10=28?

zepp · Answer

Partly correct, it's an adding operation, not a subtracting operation

anonymous · Answer

2f+10=28
