The question asks, "Three apples weigh about a pound. About how much would 1 apple cost? (Round to the nearest cent.)"

However, no price per pound of apples is given in the problem. Assuming a typical price for apples would be around $1.50 per pound (since this information is often approximated), we can calculate as follows:

1. If 3 apples weigh 1 pound and the price of 1 pound is $1.50, then the cost of 3 apples is $1.50.
2. To find the cost of 1 apple, divide $1.50 by 3: $\text{Cost of 1 apple} = \frac{1.50}{3} = 0.50$

Thus, the cost of 1 apple is about $0.50.

The correct answer would be the option that states $0.50.
