1. Purpose: To organize information into charts. This will enable you to solve word problems. Homework: Finish problems on teaching worksheet. P. 122-124 1-8 all 9-15 odd

2. Using Charts Jess bought some boxes of lemonade at seventy cents per box. He bought eight fewer boxes of punch at sixty cents per box. Use a table to organize information. # x $ = cost Lemon. x 70 70x Punch x – 8 60 60(x – 8)

3. A Coin Problem Carrie has 40 more nickels than Joan has dimes. They both have the same amount of money. How many coins does each girl have? Let x = the # of coins Joan has Let x + 40 = the # Carrie has Use whole numbers for $ so you don’t have to worry about the decimals

4. Make a Chart #coins x value = total value Carrie x + 40 5 5(x + 40) Joan x 10 10x Make an equation. 5x + 200 = 10x (They = each other) 200 = 5x (sub. 5x from both sides) x = 40 so J has 40 D @ C has 80 N
