What is the standard scratch? In golf, the standard scratch of a course is calculated using this formula:

(3*num_of_3_par_holes + 4*num_of_4_par_holes + 5*num_of_5_par_holes) - difficulty_rating


Your task is to calculate the standard scratch of a golf course, given these 4 inputs.

You should take input in any standard form in the format

[num_of_3_pars, num_of_4_pars, num_of_5_pars], difficulty rating


but if it saves bytes, you many take input in a different way.

You should output the final result by any accepted method on meta, such as returning from a function.

Shortest code wins because this is code-golf!
Scratch, 145 bytes

-??? because writing it in Oto is shorter than English

(Because Scratch is the standard scratch.)



Here's a sample run:
