Solution

Twenty-nine muffins had nuts.

Explanation

Step 1. Find out how many muffins each person made.

• Given: Glen made 16 muffins.
  
  
• Catrina made 1 less muffin than Glen. So Catrina made 15 muffins.
  
  
• Lisa and Meg each made 3 more muffins than Catrina. So Lisa and Meg each made 18 muffins.
  
  
• Find out how many muffins Wayne made.
  
  
• First, add the number of mufffins made by the other children.
  16 + 15 + 18 + 18 = 67 muffins.
  
  
• Next, subtract this number from the total number of muffins.
  87 − 67 = 20
  Wayne made 20 muffins.

Step 2. Make a chart.

	Glen	Catrina	Lisa	Meg	Wayne
Number of muffins in all	16	15	18	18	20
Fraction with Nuts
Number of Muffins with Nuts

Step 3. Add clues to the chart.

Write the fraction of muffins that had nuts. Complete the chart.

	Glen	Catrina	Lisa	Meg	Wayne
Number of muffins in all	16	15	18	18	20
Fraction with Nuts
Number of Muffins with Nuts	4	5	6	9	5

Step 4. Find the total number of muffins with nuts.

Add the number of muffins with nuts made by each person to find the total number of muffins with nuts.

4 + 5 + 6 + 9 + 5 + = 29

Twenty-nine muffins had nuts.
