The setup fee for a photo book is $15. The paper is an additional charge of $.17 per page. What is the greatest number of pages that a book can have if the total bill is to be less than $40?

Select the correct answer. lisa and daisy work at a hair salon. the salon charges $18 for a hair styling session with lisa and $12 for a session with daisy. the income on a certain day is projected to be $216. this situation can be represented by the equation 18x + 12y = 216, where x is the number of lisa's customers and y is the number of daisy's customers. how many customers would lisa need to serve to attain the projected income if daisy calls in sick that day? (note: x ? 0, y ? 0, and x and y take only integer values.)
