My name is Mahad Adam Botan, I am 37 years old business expert. I have been studying on the marekting and wanted to introduce mathematical orientation for the original marketing mix which is fouded in earlier of 1960 namely the four Ps. As you know, nowadays there have been 7Ps and 9Ps, this has created confusion on my research and I have decided to maintain my study on the four marketing mix: product, price, place and promotion. So I want to know how leaving these other marketing mix components behind will have effects on the validity of my research. In addition, I am not a mathematician and I want to introduce mathematical formula which the SMEs can use to calculate finding the optimal mixture of the four Ps where they can earn more profits and complete strongly in th market. And my question here is there anyone who can help me to produce something with good and acceptable arithematic orientation. 

Cheers,

Mahad
