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
The distributive property works like this:
a(b+c) = ab + ac
To split apart bigger numbers, you can change 45 into 40+5. Writing this using the distributive property looks like this:
6(40+5)
Now, like we did above with a, b, and c, you can rewrite it to this:
(6 x 40) + (6 x 5)
So, your answer is B.
