Karen earns 43 dollars per week working pt at a bookstore. she makes one dollar more for each book she sells. the amt A, in dollars that Karen earns in a week ifshe sells b books is given in the function A(b) =43 + b how much does she earnin a week if she sells 22 books?
To find out how much Karen earns in a week if she sells 22 books, plug in the value of b (which is 22) into the function A(b) = 43 + b.
A(b) = 43 + b
A(22) = 43 + 22
Now, let's evaluate the expression:
A(22) = 43 + 22
A(22) = 65
Therefore, Karen earns 65 dollars in a week if she sells 22 books.
To find out how much Karen earns in a week if she sells 22 books, we need to substitute the value of "b" (the number of books she sells) into the function A(b) = 43 + b.
So, let's substitute b = 22 into the function:
A(22) = 43 + 22
Now, we can simplify the equation:
A(22) = 65
Therefore, if Karen sells 22 books in a week, she will earn 65 dollars.
You know that
A(b) = 43+b
so, if b=22, plug that in wherever there is a b:
A(22) = 43+22
