Problem Statement
The project’s purpose is to work out the best level of production to suit the new packaging for ‘Trini Chocolate Delights ltd.’ The company’s objective is to maximize produce of their new product but minimize manufacturing cost. To fulfill this task the use of calculus is needed along with other mathematical methods to help design a best suitable and cheap packaging that will be used to carry a grand amount of smaller products while cost remain in a stead/safe amount.

Mathematical Formulation

Below is a list of formulas applied to each question

A. Tan =
-

B. Substitution
Area of triangle + Area of rectangle= Area of pentagon

C. Differentiation

OR

E.

Problem solution

E B

ycm

D 8xcm C

i) F is the mid-point of line EB and it’s also the perpendicular of triangle EAB. The line AF cuts triangle EAF in half resulting in two isosceles triangles. Since AFB= AFE and DC=EB, then FB and EF are both equal to 4xcm. , , then

Therefore

ii) Since the total cross-sectional area is 90cm then:
(i)

(ii)

Make y the subject in equation (i)

Now sub (i) into (ii)

Maximum area

When x=3 the maximum area:

Therefore the maximum cross-sectional area is 540

When the equation is divided by 60 it becomes:

Therefore

These are the two possible values of x that satisfies the maximum cross-sectional area being 300

Prism length=5cm
x=1
Since x=1, cross-sectional area=300 and cross-sectional perimeter=90cm Volume of prism=
=

When the sides of the container is opened up it makes a net consisting of 7 faces, 2 pentagonal faces and 5 rectangular faces.

Length=Cross-sectional perimeter=90cm
Width=prism length=5cm

Therefore

Area of rectangles=590
=450

Total surface area (sum of the areas of each face) = Cross-sectional area+ area of rectangles =300(2) +450
=1050

Fixed costs=\$6000
Variable costs= and
Average costs (AC) =

For average cost to be a minimum

X=600{Therefore 600 units has to be produced to maintain average cost at its minimum level.}

Since x=600 gives a minimum value

Application of Solution
Since x (the number of units produced) is equaled to 600, the average cost of the product using the formula:

Therefore the possible minimum average cost is \$25 per unit

Conclusion

It was determined that the Trini Chocolate delights ltd. had to produce 600 units at the minimum average cost of \$25 per tin of chocolates. Also the maximum cross-sectional area was determined to be 300 if the value of x was either 5cm or 1cm.
