That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.
Yeah Imao you usually do these type of questions on a calculator but I've tried writing it on a calculator and it keeps on saying "error" so I'm gonna guess the question is wrong or sth
but if you type out the question without the bracket before the 12 you'll get 6.63
anyway hope this helps- have a good day bro cya)
Where is the problem at? give me the url
