Okay. So, we are talking about 89¢ per container as singles. There is a case of 12 for $8.64. To find the unit price per container for that, we can divide the price by the number of containers. 8.64/12 is 0.72. That's 72¢ per container by the case. That's cheaper than buying it by a single. Let's subtract. 89 - 72 is 17. There. 17¢ per container is saved by buying the oil case.
I think is C tbh sorry if that’s wrong my fault
After a year the
population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after
1 year it will be: <span>
3800 x 0.986
after 2 years it will be:
3800 x 0.986 x 0.986...
after 3 years: 3800 x (0.986)^3
<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 =
which is 3591.62724 or 3592</span></span>
