My experiment and method

I rode my bike down to the shops and bought 4 well known brands. They did not have hubba bubba so I just another brand called P.K. 5gum cost me $2.50, P.K cost me $1.20, Juicy fruit cost me the same as P.K and extra cost me $2.00. From this point i thought 5 gum would have the longest lasting flavour and juicy fruit or p.k would have the shortest lasting flavour.
My next step was to find out how much grams each piece of gum brand contains. On the package i read that 5 gum had 12 pieces in the package and in total of 32g. So i did the math.
5gum - 32 g \ 12 pieces = 2.7 but i also added a extra 0.1 g in = 2.8 g
p.k - 14 g \ 10 pieces = 1.4g. I then added in another piece of P.K - 1.4 x 2 = 2.8g
juicy fruit - 14 g \ 10 pieces = 1.4g I then added in another piece of Juicy fruit - 1.4 x 2 = 2.8g
extra - 27g \ 14 pieces = 1.9g. I then added in another piece of extra - 1.9 x 2 = 3.8g After that i cut off 0.5g off each extra piece - 3.8 - 0.5 - 0.5 = 2.8g
So now it is even, all pieces are 2.8g each. I took pictures before my experiment for my blog and scaffold.
Then I chewed the gum and recorded the time it finishes its flavour. I drew a table for my result. My result was that extra had 4:10, 5 gum had 2:08, P.K had 2:11, and juicy fruit had 1:37.
