Given that the spread sheet has been modeled by the equation PV=k, taking points (P,V) from the spread sheet such as (140,100) and substituting in the equation, we find the value of k as:
k=140*100=14,000
thus our equation can be written as:
14000=PV
thus when V=62, P will be:
14000=62P
solving for P we get
P=14000/62
P=225.81
