Hii!
The answer would be $0.35.
Hope this helps :)
If you want me to explain, ask me in the comments.
Answer:
c÷0.35
Step-by-step explanation:
Because you are trying to find the amount it costs for 1s, you need to divide 0.35s by 0.35 to get 1s, and you need to divide c by 0.35 as well. So, you get c÷0.35
