A. C= 0.1d + 30
because if u take the point (100,40), then d= 100 and c=40. Now 0.1d means = 10 and 10 + 30 gives 40 which is equal to C.

Yes, it will always be a rational number. I'll expound on this by defining what a rational number is. It is any number that can be expressed as a fraction. Otherwise, it is called an irrational number with a non-terminating decimal expansion. So, although 1/3 has a non-terminating decimal expansion because it is equal to 0.33333333...., it is still a rational number because it can be expressed into a fraction.
