At an elevation of 1221.4 feet, Lake Mead will hold 28,945,000 acre-feet of water. Which number is the best estimate of this amount of water?

3 · 10⁷ = 30,000,000

Step-by-step explanation:

3 · 10⁶ = 3,000,000

2 · 10⁷ = 20,000,000

3 · 10⁷ = 30,000,000

2 · 10⁸ = 200,000,000

The closest answer to 28,945,000 is 3·10⁷
