Start off by defining some variables. So lets set f = number of fancy shirts bought and lets set p = number of plain shirts bought Can you formulate some equations using these symbols?

e.g. you are told that the total umber of shirts bought is 7. So if you bought 'f' fancy ones, and 'p' plain ones, then we can say that:\[f+p=7\]

now, since there are two unknowns here (f and p), we need two equations in order to solve this.
