Problem 2: School Penny Collection
Step 2: Convert pennies to dollars
- Total money collected = $$10,000,000 \times \frac{1}{100} = \$100,000
- Total pennies collected = 10 million
Final Answer
Problem 3: Millions in a Billion Step 1: Define a billion - 1 billion = 1,000 million Problem 4: Blog Creation Rate Step 1: Calculate blogs per second - 2 blogs created per second Step 2: Calculate seconds in 30 days - 1 day = 24 hours - 1 hour = 60 minutes - 1 minute = 60 seconds - Total seconds = 30 \times 24 \times 60 \times 60 = 2,592,000 seconds Step 3: Calculate total blogs - Blogs per month = 2 \times 2,592,000 = 5.184 \times 10^{6} Problem 5: State Deficit Per Person Step 1: Calculate total deficit - State deficit = \$2.3 billion = \$2,300,000,000 Step 2: Calculate per person contribution - State population = 3 million - Contribution = \frac{\$2,300,000,000}{3,000,000} = \$767
