7–2 Name Reteach Date Problem–Solving Skill: Reasonable Answers Jeff wants to invite some friends over for dinner. He has a large rectangular table and knows there is room to seat 10 people on each of the long sides and 4 on the two ends of his table. 4MR3.1, 4NS3.0 Chapter Resources If Jeff wants everyone seated at the table, how many friends can he invite? Is it reasonable for him to invite 40 people? Step 1: Understand. What facts do you know? Jeff can seat 10 people on each of the long sides of his table. Jeff can seat 4 people on each of the ends of his table. Jeff wants everyone seated at the table. Copyright © Macmillan/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. Step 2: Plan. What you need to know? How many friends is it reasonable for Jeff to invite? Step 3: Solve. What math do you need to do? You need to figure out the number of people that can sit at the table, based on all of the amounts that you have. 2 long sides, 10 people each: 10 × 2 = 20 2 ends, 4 people each: 4 × 2 = 8 Add the amounts: 20 + 8 = 28 people can sit at the table. Step 4: Check. See if your answer makes sense. When you compare the amount that can sit at the table, 28, to the amount of people that Jeff wants to invite, 40, you can see that it is not reasonable for him to invite 40 guests. If Jeff only has seats for 28, how many friends should he invite? (Remember, Jeff needs a seat too!) Use the steps above to solve the following problem. Brittany was given 3 movies to watch in her free time. Each movie is 100 minutes long. Brittany has 70 minutes to relax before she goes to work every day, Monday through Friday. Is it reasonable for her to expect to watch all three movies, starting Monday and ending on Friday? Grade 4 117 Chapter 7
