Chapter 1 – Expressions, Equations, and Functions Algebra I A - Meeting 3 Section 1.5 – Use a Problem Solving Plan PROBLEM SOLVING PLAN READ AND UNDERSTAND Read the Problem CAREFULLY!!! STEP 1 : Identify Variables and Constants. What is the problem asking? ORGANIZE YOUR THOUGHTS Formulate an Approach. STEP 2 : Make an equation, inequality or expression. SOLVE THE PROBLEM Evaluate the equation, inequality or expression STEP 3 : CHECK YOUR WORK DOES IT MAKES SENSE!!! STEP 4 :

Chapter 1 – Expressions, Equations, and Functions Algebra I A - Meeting 3 How many tons would it take to make enough gas to fill a car’s 20 gallon gas tank? Homework # 2 – Word Problems pg 19 #32 Fossil fuels are produced by the decay of organic material over millions of years. To make one gallon of gas it takes about 98 tons of organic material, roughly the amount of wheat that could be harvested in a 40 acre field. Write an expression for the amount (in tons) of organic material it take to make g gallons of gas. pg 19 #35 What is the total cost if 7 birds are exhibited? A wildlife center presents a program about birds of prey. The center charges a abasic fee of $325 and an additional fee for each bird exhibited. If 5 birds are exhibited, the additional fee is$ 125.

Chapter 1 – Expressions, Equations, and Functions Algebra I A - Meeting 3 Then find the time your printer would take to print 12 small photos and 5 large photos. Homework # 2 – Word Problems pg 19 #36 Your printer takes 36 seconds to print a small photo and 60 seconds to print a large one. Write an expression for the time (in seconds) your printer would take to print a batch including both small and large photos. pg 25 #40 You buy 15 CDs. Will they all still fit? You buy a storage rack that holds 40 CDs. You have 27 CDs. Write an inequality that describes how many more CDs you can buy and still have no more CDs than the rack can hold.

Chapter 1 – Expressions, Equations, and Functions Algebra I A - Meeting 3 Homework # 2 – Word Problems pg 25 #42 You are baking batches of cookies for a bake sale. Each batch takes 2.5 cups of flour. You have 18 cups of flour. Can you bake 8 batches? Explain. pg 26 #45 b) If you spend the same amount of time at each job, will you meet your goal? Explain. You have two part-time jobs. You earn $6 per hour running errands and $5 per hour walking dogs. You can work a total of 10 hours this weekend and hope to earn at least $55. Let r be the number of hours you spend running errands. a) Write an inequality that describes the situation. Your inequality should involve only one variable, r. c) Can you meet your goal by working all 10 hours at only one job? Explain.
