3*pie (or p) + 20

It is $5 per pie.

We know the answer has to end is 0 or 5 since all multiples of 5 end it those. The first time 3 goes into 0 or 5 is 15. (3*5=15). You substitute to get 3*5+20=35. You sell 7 pies because 7*5=35, which is the cost for the making of the pies and the rolling pins.
