I'm not really sure what the question is here, because you just gave a statement... but if you are trying to get an expression from words, here is what it would be:
A = 10N
I'm also not sure if "a number" is equal to the same as "a number" at the end, but I'm guessing not. If it is though, and you're trying to find the value of A, the answer would be:
A = 10

Answer:
Your answer should be $29.40
Step-by-step explanation:

Therefore, your total cost for 7 books will be $29.40
