OKAYYY. Well ill show you how to make the equations for 5 and you should be able to apply the same method to the other ones. Let \(q\) represent quarters Let \(d\) represent dimes Let \(n\) represent nickels So you have \(12.25=q+d+n\) And you have Equation 1. \(2n+5=d\) Equation 2.\(3n-1=q\) So you have \(12.25=(3n-1)+(2n+5)+n\) And you can use this to find nickels and when you do, plug into Equations one and two to find dimes and quarters
