Hey guys
Could someone please explain how to do this question
 
An assessment task has 25 multiple choice questions each with four alternate answers.
Each question answered correctly is awarded 4 marks, and if any question is answered incorrectly, 2 marks are deducted from the total awarded.
If all questions are attempted on the task:
- Show that if n are answered, the number of marks awarded can be given by: 6n-50

Thankyou
