Question

Many years ago, a cruise liner sank in the middle of the Pacific Ocean. The survivors luckily landed on a remote desert island. There was enough food for the 220 people to eat once per day; this would make the food last for three weeks. Six days later a rescue ship appeared, unluckily this ship also sank, leaving another 55 people stranded on the island to now share what remained of the original food. The food obviously had to be rationed again. Everyone was now on one-half of the original ration; so how many days in total would the food last for, from the day of the original sinking?

Answer 1

Let r be the original ration. Write everything in terms of days, and try to come up with an equation. What do you get?

Answer 2

r=220x21

Answer 3

Can anyone help me???????
