What percentage was spent in each category if network TV totaled 20.4 billion local TV 16.2 billion and cable TV 12.3 billion?

To find the percentage spent in each category, first calculate the total spending: 20.4 billion (network TV) + 16.2 billion (local TV) + 12.3 billion (cable TV) = 48.9 billion. Then, divide each category's spending by the total and multiply by 100: Network TV: (20.4/48.9) × 100 ≈ 41.7%, Local TV: (16.2/48.9) × 100 ≈ 33.1%, Cable TV: (12.3/48.9) × 100 ≈ 25.1%.
