Do simple beginner level C Homework

I need someone to do entry level programs. I have 4 problems total, some have 2 parts. If you are someone familiar with C (NOTE: This is to be done in C, not C++) this will super easy. Example problem: 1) Write a main program and 2 functions to compute and print out the mass of a balloon that is inflated to a volume V, at a pressure P and a temperature T. The main program will read in the input P, V and T. a. One function should calculate the mass of the balloon (M) from the following formula : PV = 0.42M (T + 460) b. The second function should print out the values of P, V, T and M These programs can be super simple as possible and dont need to be perfect. Please contact me if you are interested in doing these. I'm not going to pay much as they are easy. Maybe 40-60$ to do them all. Like I said, they don't need to be perfect. If interested I will email you all the work.
