I have a question that I'm really stuck on at the moment.
A chocolate factory will sell a new chocolate bar with a weight of 100g.
They will sell for $2.00 each and 300 000 will be sold each week. For every price rise of 10c, sales will drop by 5 100 bars per week.
Manufacturing cost is 50c/100g of chocolate, + 0.213 cents/cm^2 for the wrapping.
The shape of the chocolate bar is an equilateral triangular prism.
We have to:
a) find an expression for 'h' (perpendicular height of the prism) in terms of 'b' (base length)
b) fins expression for 'A' (area of equilateral triangle) in terms of 'b' [would this just be A=1/2 bh?]
c) find equation for surface area in terms of b
d) find the dimensions of the chocolate bar.
I'm really confused on this and have no idea where to start. Any help would be greatly appreciated
