Answer:
The better bargain is the case of twelve 12 ounce cans.
Step-by-step explanation:
<u>2-liter bottle of soda:</u>
67.6 ounces cost $1.89, then
1 ounce costs
<u>A case of twelve 12 ounce cans:</u>
ounces of the same soda cost $2.99, then
1 ounce costs
The better bargain is the second choice, the case of twelve 12 ounce cans.
The volume formula is length x width x height. 7x5x12=420 cubic inches
16y² - x² = 4²y² - x² = (4y)² - x² = (4y-x)(4y+x) ← dfference of squeares
