It say MULTIPLY the (HOURS) of labor by ($50) then ADD $35

So 

50 (h) and + 35

So if you're directly multiplying h by something, you can use some deductive reasoning here, and get rid of any of the options that don't have h being multiplied by 50. So, c, you can get rid of because you know that you're not multiplying h by 35. You can get rid of a and b because neither of those have h being directly multiplied by something. So the last option is d. So you're multiplying the hours (h) by 50$. So 50h and then adding 35$. So 50h + 35.
