Solution
The correct option is A 0.995 dollars
Price of 100 lb of all-purpose flour = 99.50 dollars
Price of 1 lb of flour = 99.50 ÷ 100
To divide a number by 100, we have to move the decimal point two places to the left.
⟹ 99.50 ÷ 100 = 0.995
Hence, the price of 1 lb of flour = 0.995 dollars
Price of 100 lb of all-purpose flour = 99.50 dollars
