First, we need to convert the price per ounce for both options. For the 12-oz can: 
89 cents / 12 oz = 7.42 cents/oz

For the 2.00 L bottle: 
$2.29 / 2.00 L = $1.145/L 
$1.145/L x 1.057 qt/L x 32 oz/qt = 36.71 cents/oz

To find out how many times more expensive the can is, we divide the cost per ounce of the bottle by the cost per ounce of the can: 
36.71 cents/oz / 7.42 cents/oz ≈ 4.95

Therefore, buying a 12-oz can of soda pop is approximately 4.95 times more expensive than buying a 2.00 L bottle. Closest to this number is 2.2, which is the answer B.
