Question

A company decided to sell chocolates bars at the value of the weighted mean of price. How do i calculate weighted mean of price using sales as the weight? For how much should the company sell its chocolate bar? for example
Price Sales
2.50 125
3.75 316
4.25 471
5.10 128

Answer 1

I believe the point of this question is to find what the average bar should sell for. Then you would take the sum
\[(\sum(price)*(sales))\div sales\]
or
(2.50*125) + (3.75*316) + ... + (5.10)*(128)
-------------------------------------
125+316+...+128

Answer 2
