You can put this solution on YOUR website!
bakery A sold 300 cupcakes in 12 days then sold 450 cupcakes in 18 days.
rate = 450/18 = 25 (cakes/day)
-------------------------------------------
bakery B sold 120 cupcakes in 5 days, then sold 200 cupcakes in 8 days.
rate = (120+200)/(5+8) = 320/13 = 24.61 (cakes/day)
