31. In a Mathematics competition, there are 10 questions of equal marks. You get 10 marks for a correct
answer, lose 8 marks for a wrong answer, or no mark for each blank answer. If Jimmy answered 3
questions correctly, 6 questions wrongly, and left 1 question unanswered, how many marks could he
get?

Respuesta :

Jimmy will receive -18 marks in the mathematics competition.
3*10=30
-8*6=-48
30+-48=-18
