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.
No it is not greater than 0.88
The answer if 7 numerator and 20 denominator you need to find common multiples
D(1/x)/dx= d(x^-1)/dx
= -x^-2
the derivatives of the two cases you mentioned is as follows:
(I) f(x)=k/x
d{f(x)}/dx= k×(-x^-2)
= -kx^-2
(ll) f(x)=x/k
d{f(x)}= d(x/k)/dx
= 1/k
you can just simply take out the constant from the derivative and multiply it to the final answer of the derivative of the given function.
