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
