Question One: Story Problems

a. Say the city council levies a 0.3% tax on hotel rooms if you spend the night in a room that costs

$65/night, how much will you pay in city tax?

b. Nancy gets to work at 7:45 am and stays until 10 pm, taking an hour for lunch during the day. She gets paid $11/hour for the first 8 hours, and time and half after that. How much money did Nancy make in her workday?

c. You are purchasing an accounting textbook that costs $90. If sales tax is 6.25% and you have $100 in your pocket, how much do you get back in change?

d. Pham cam work as many or as few hours as she wants at the college bookstore for $9 per hour. But due to her hectic schedule, she has just 15 hours a week that she can spend working at either the bookstore or other potential jobs. One potential job, at a caf, will pay her $12 per hour for up to six hours a week. She has another job offer at a garage that will pay her $10 an hour for up to 5 hours per week. And she has a potential job at a daycare center that will pay her $8.50 per hour for as many hours as she can work. If her goal is to maximize the amount of money she can make each week, how many hours will she work at the bookstore?
