A bookstore marks up the price of a book by 40% of the cost from the publisher. Therefore, the bookstore's price to the student, P(x) (in $) after a 7.5% sales tax, is given by P(x) 1.075(x + 0.40x), where x is the cost of the book from the publisher. Evaluate P(60) and interpret the meaning in the context of this problem.

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
