Question

PLEASE ANSWER + BRAINLIEST!!!!

Answer 1

Answer: aₙ = [d-(d-n)]*10

where n is the number of questions answered correctly and d is the total amount of questions.

Step-by-step explanation:

By understanding the question we can tell than she will be rewarded for each corrct answer. so, how many wrong answers she/he can have?

d-n= Total number of wrong answers

d- (d-n) = Total number of correct answers

price: 10 for each correct answer, so:

price: [d-(d-n)]*10

Therefore:

aₙ = [d-(d-n)]*10
