What’s the answer ->Score with 6 questions wrong: ? And score with x questions wrong :?

Answer 1

Answer:

14 *5 = 70

(20-x)*5 or 100-5x

Step-by-step explanation:

So first let's calculate how many questions are in the total test

100 total point/ 5 point = 20 questions

So if Mei Mei got 6 questions wrong, she answered 20-6=14 questions correct

14 *5 = 70

So if Mei Mei got x questions wrong, she answered 20-x questions correct

So the general formula would be (20-x)*5 or 100-5x
