<em>What is the number sentence for "1 less than n is the sum of z and 2?"</em>
<em> </em>
<em> </em>
❖ First, Notice it says "1 less than n". This expression indicates that
we subtract 1 from n, which looks as follows:-
❖ Now, It also says "the sum of z and 2". This indicates that we add z and
2:-
❖ Now, Combine these two little expressions into one equation:-

Answer:
419.25
Step-by-step explanation:
The calculation of the cost of materials for the cheapest such container is shown below:-
We assume
Width = x
Length = 2x
Height = h
where, length =
Base area = lb
=
Side area = 2lh + 2bh
= 2(2x)h + 2(x)h
= 4xh + 2xh
Volume = 24 which is lbh = 24
Now, cost is
now we have to minimize C(x)
So, we need to compute the C'(x)
C"(x)
now for the critical points, we will solve the equation C'(x) = 0
So, x is a point of minima that is
=
Now, Base material cost is
= 139.75
Side material cost is
= 279.50
and finally
Total cost is
= 139.75 + 279.50
= 419.25
