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.

So, make use of the other piece of information given to you to formulate the second equation

If Fancy shirts cost $28 and you bought 'f' fancy shirts, then what will be the total cost of fancy shirts?

$28 is cost of ONE fancy shirt
