Class Date Chapter 5 Project: The Choice Is Yours Beginning the Chapter Project Do you have a job? If not, what will your first job be? What expenses will you have? How much money will you actually earm? How can you compare earnings between two jobs? Linear equations can help answer all of these questions. As you work through the activities, you will make graphs and write equations that model earnings for different jobs. After interviewing someone about his or her first job, you will choose a job that you might like and will explain why you made that choice. List of Materials . Calculator Graph paper Activities Activity 1: Graphing Find the starting hourly wage for two jobs that interest you. · For each job, write an equation that gives the income y for working x hours. With hours worked (0 to 10) on the horizontal axis and income on the vertical axis, graph your two equations Suppose you work eight hours in one day. Explain how your graph shows the difference in income for the two jobs. Activity 2: Modeling Suppose you earn $8.50/h at a bakery. From your first paycheck you determine you earn $8.50/h at a bakery. From your first that $2.15/h is withheld for taxes and benefits. You work x hours during a five-day week and you spend $3.75 each day for lunch Write an equation for your weekly earnings after taxes, benefits, and lunch In this situation, what do the slope and the y-intercept represent? How many hours must you work to earn $120 after taxes, benefits, and lunch Prentice Hall Algebra 1 Teaching Resources Copylight O by Pearson Education, inc, or its afffiates All Rights Reserved

Solution

2)

Equation for savings/ weekly = (Income - Taxes - Expenditure )* no of working das per week* no of hours working per day

= (8.5-2.15-3.75)*x*5 = 13x

b)

Slope = 13 and intercept = 0

c) 120 = 2.6 x (Only hours)

x = 46.15 hrs
