20

dollars 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 Ahmad earns in a week if he sells

b

books is given by the following function.

=Ab+20b

Yep, the problem is ambiguous and no real question is provided.  "20b" would not represent $20 per book, it appears that the real equation to work with would be:

T=20w+b

where 'w' is the number of weeks, 'b' is the number of books and 'T' is the total amount earned.
