There were a total of 88 questions in a school Science test. 6 marks were awarded for each correct answer and 2 marks were deducted for each incorrect answer or incomplete answer. Shannon could not complete all the questions in time and left the last 18 questions blank. She scored 272 marks. How many less wrong or incomplete answers than correct answers did she answer?

Correct answers	Marks awarded (x6)	Wrong or incomplete answers	Marks deducted (x2)	Difference
70	420	18	36	384
69	414	19	38	376

Number of questions completed
= 88 - 18
= 70

Big difference
= 384 - 272
= 112

Small Difference
= 384 - 376
= 8

Number of wrong answers
= 112 ÷ 8
= 14

Number of wrong and incomplete answers
= 14 + 18
= 32

Number of correct answers
= 88 - 32
= 56

Number of less wrong or incomplete answers than correct answers
= 56 - 32
= 24

Answer(s): 24
