Answer:
15 times as long
Step-by-step explanation:
6 meters/0.4 meters is 15, so it is 15 times as long.
Answer: 6-pack.
Step-by-step explanation:
assuming there’s no tax, the 6-pack would offer the best price per roll.
for 12 rolls w/ the 6 pack it’d be 10.80 which divided by 12 is .9(0)a roll. Where as the 12 for 11 is roughly .91 . So the 6-pack is a better offer.
