Problema Solution
The total cost of growing 800 kilos of tomatoes per week is $1,500 and of growing 1,000 kilos of tomatoes per week is $1,800. Determine the cost equation assuming a linear model.
Answer provided by our tutors
suppose the linear model is y = kx + b y is money x is kilos
so we know two points (800,1500) and (1000,1800)
1500 = 800k +b
1800 = 1000k + b
so 200k=300
k =1.5 b=300
the linear model is y = 1.5x +300
