# How to construct linear model?

Jan 12, 2018

$\text{see explanation}$
color(white)(x)$775to120rArrk=775/120=6.458.... color(white)(x)$975to160rArrk=975/160=6.093....
$\text{consider the difference}$
975-775=$200" and "160-120=40 $\Rightarrow k = \frac{200}{40} = 5$$\Rightarrow C = 5 n$$C = 5 \times 120 = 600 \text{ and }$$C = 5 \times 160 = 800$"now "775-600=$175" and "975-800=$175 "sum already in counter "=$175
