Answer: 1.5 x 10^6 (A)
Step-by-step explanation: $4,500,000 divided by 1/3 (Stocks), gives us $1,500,000. We need to reach the first digit of 1,500,000 (1) and in order to do that we have to count the number of zeros. Move the decimal place back from the end of 1,500,000 until you reach the first digit (1). That should give us 6 zeros, or (6 times). Now we are left with a simplified version, in other words, the answer is 1.5 x 10^6.
