A is $0.70.
You can divide $5.60 by 8 to get how much it costs for 1 meter.

B is $5.60 divided by R = C
I got this because $5.60 was divided by 8 (the length of the ribbon) and I got how much it costs.

C. If R is 9, and the price of the R per meter is still $0.70, then multiply 9 and $0.70 for $6.30
