H (t )=2t+100

Question

I've been confused about this question for a while and I need the answer so then I can figure it myself 

Answer 1

H(t )=2t+100 is a function called H (it might be the total cost of making "t" units of a product that uses $100 of material and takes 2 hours for assembly).  Plug in any t value to get the result.
