Answer:
14 minutes
Step-by-step explanation:
4 x every 100 bottles
100, 200, 300 = 3
4 x 3 = 12
if 4 minutes is for every 100 bottles, then 50 is half of 100. so 4 divided by 2 is 2
12 + 2 = 14
So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:

Now, in this situation we can make use the elimination method by converting 3n to -27n.

Add both equations:

So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:

So one order of nachos cost $1.40.
The solution to the problem is as follows:
<span>'(t) = 0 gives:
-24t + 60 = 0
t = 2.5
For this t, the second derivative s"(t) = -24 is negative.
And so, s(t) is maximum for t = 2.5.
Maximum height is:
S = -12(2.5)^2 + 60(2.5) +8 = 233ft
