ANSWER

EXPLANATION
If y varies directly with x, we write the mathematical statement;

When we introduce the constant of proportionality k, then we write the equation,

If y is 2.5 when x is 5,then we have;



The equation of variation then becomes;

when x=14,


For that question the answer is 40nickels/standard coin
