Hi !

You have to make a system of equations ! For Tony, it's going to look like this :

\[3x+5y=7\]

Here, \(x\) is the price of one coffee and \(y\) the price of one cookie. You will have to do the same with Joe and solve the system. If you want more information on how to do it, please visit this link :

If you have any other questions, feel free to ask them !
