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
I suppose we make it an improper fraction? Multiply the whole number by the denominator and then add the numerator
1 * 4 + 3 = 7
Put it over the denominator
7/4
