Question 1001732
You have two points
(50,324)
(70,415)
Generate the equation of the straight line. 
Then solve for the value at 95.
Find the slope.
{{{m=(415-324)/(70-50)=91/20}}}
Then using the point-slope form,
{{{y-324=(91/20)(x-50)}}}
Then,
{{{y-324=(91/20)(95-50)}}}
I'll leave you to solve for y to get the final answer.
