Question

Which of the following equations represents the total cost, C, for the number of sandwiches, S, where each sandwich costs $7?

1) S = 7C
2)C = 7S
3) S = 7/C
4) C= 7/S

Answer 1

I’m thinking a because your not dividing

Answer 2

Total cost is C

No of sandwiches is S

Each S costs $7

So equation is number 2 (C = 7S)
