Solution
The correct option is A 20 dollars
The price of flour given for different quantities 3, 6, 9, and 12 lbs are 4, 8, 12, and 16 dollars, respectively.
The difference between the first and the second terms of the price = 8 - 4 = 4 dollars
The difference between the second and the third terms of the price = 12 - 8 = 4 dollars
The price of all-purpose flour is following a pattern.
To find the next term in the sequence, we have to add 4 to the term.
Hence, price of 15 lb of flour = 16 + 4 = 20 dollars
