It would be 110x because they are like units, so they can be added together. Really, you are just doing 80 plus 30, and then adding an x on the end.
C I think I hope this is correct
Integer
because step-by-step-equation
It should be 15% I think I’m right
I would think the value would be .2 cause if you had 100 tosses you would expect 60 value for heads and -40 value for tails. giving you 20/100
