We can make a system of equations:Joseph: 4n+3p=11Patrick: 3n+5p=11Luckily enough, they are both equal to 11, so this is easy to solve. Just put the two together like this and solve for n:4n+3p=3n+5pn+3p=5pn=2pPlug 2p into either equation for n:4(2p)+3p=118p+3p=1111p=11p=1So a pen is $1, and that must mean a notebook must be $2 because it costs twice as much as a pen.Hope this helped!
