Maya earns 43 dollars per week working part-time at a book store. She makes one dollar more for each book that she sells. The am
ount, A (in dollars), that Maya earns in a week if she sells b books is given by the following function.
A (b) = 43 + b
How much does Maya earn in a week if she sells 13 books?
It says that Maya makes one dollar more for each book that she sells so if she sells 13 books, she will make 13 dollars more than her weekly earning which is 43 dollars. So to find the answer, you would need to add 13 + 43 which would equal 56 dollars.
