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

3. elexusvanderhorst

18

4. zepp

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

5. elexusvanderhorst

9

6. zepp

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

7. elexusvanderhorst

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

8. zepp

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

9. zepp

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

10. elexusvanderhorst

yes

11. zepp

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

12. zepp

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?

13. elexusvanderhorst

so which equation 2f-10=28?

14. zepp

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

15. elexusvanderhorst

2f+10=28

16. zepp

Yep you got it

17. elexusvanderhorst

ok thank you so much
