Khamis earns 55dollars per week working part-time at a book store. He makes one dollar more for each book that he sells. The amount, A (in dollars), that Khamis earns in a week if he sells b books is given by the following function.

A(b)=55+6

How much does Khamis earn in a week if he sells 32 books?

It is not

A(b)=55+6
It is
A(b)=55 + 6*b
so
A(32) = 55 + 6*32

one dollar more for each book that he sells

means that A(b) = 55+b

"math" needs to learn the difference between "6" and "b"

To find out how much Khamis earns in a week if he sells 32 books, we can plug the value of 32 into the function A(b) and simplify it.

The given function A(b) = 55 + 6 tells us that Khamis earns a base amount of $55 per week, and then an additional $6 for each book he sells (b).

To calculate the amount Khamis earns if he sells 32 books, we need to substitute b = 32 into the function:

A(32) = 55 + 6 * 32

Now we can simplify the expression:

A(32) = 55 + 192

Adding 55 and 192 together gives us:

A(32) = 247

Therefore, Khamis will earn $247 in a week if he sells 32 books.
