An analyst analysed 102 trips of a travel company. He studied the relation between travel expenses ($y$) and the duration ($x$) of these trips. He found that the relation between $x$ and $y$ was linear. Given the following data, find the regression equation of $y$ on $x$. $\sum x = 510, \sum y = 7140, \sum x^2 = 4150, \sum y^2 = 740200, \sum xy = 54900$
