Answer:
c=3r
Step-by-step explanation:
If you really can't figure it out, you can start plugging in numbers for each value. For instance in the first possible answer: c=r+3 , you can plug in 2 for r and 6.00 for c to get 6.00=2+3. (2 and 6 are both starting values in the table) this doesn't make sense because 2+3 is 5, so you can immediately mark that answer out. If you do the same for the rest of them, you can see that for c=3r is 6.00=3(2). This makes sense because 3(2) is 6.
