Answer 1

7.) rosa, who works at a fast food restaurant, received 9.05 in tips one afternoon, all in quarters, dimes, and nickels. there were ten less dimes than quarters and five less nickels than dimes. how many of each kind of coin was there?

Answer 2

I NEED THREE equations per question.. is all

Answer 3

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
