Question 727267: I need to write and equation for the monthly profit P, in terms of expenses and the number of kilograms (k) sold. Bearing in mind Fixed Costs p/month of $4500 and a Variable Cost of and Extra 6.25 per kilo sold. However in part two i need to rearrange to make K the subject...
Income for each kilo sold is 25.75
Do you think my equation is ok for this purpose?
I have written P=(k*25.75)-(k*6.25+4500)
Thanks again fingers crossed.

You can put this solution on YOUR website!

P=(25.75-6.25)*k-4500
and solve for k
(P+4500)/(25.75-6.25)=k
