Find a Mathematical Model Representing the Statement $v = \frac { 0.141 p } { q s ^ { 2 } }$

Multiple Choice

Find a mathematical model representing the statement.(Determine the constant of proportionality. ) ​
V varies jointly as p and q and inversely as the square of s.(ν = 1.4 when p = 4.4,q = 7.3 and s = 1.8. )
​

A) $v = \frac { 0.141 p } { q s ^ { 2 } }$ ​
B) $v = - \frac { p q } { 0.141 s ^ { 2 } }$
C) $v = \frac { 0.141 p q } { s ^ { 2 } }$
D) $v = \frac { p q } { 0.141 s ^ { 2 } }$
E) $v = - \frac { 0.141 p q } { s ^ { 2 } }$
