Since Y varies inversely with X, we can express this relationship as ( Y = \frac{k}{X} ), where ( k ) is a constant. Given that ( Y = 4.5 ) when ( X = 3.25 ), we can find ( k ) by calculating ( k = Y \cdot X = 4.5 \cdot 3.25 = 14.625 ). Now, to find the value of X when ( Y = 3.75 ), we use the equation ( 3.75 = \frac{14.625}{X} ), leading to ( X = \frac{14.625}{3.75} = 3.9 ).
