Every year, Jada's scout troop makes and sells tie-dyed shirts to raise money for charity. Short-sleeved shirts are easier to make, so they try to sell more short-sleeved shirts than
long-sleeved shirts. Last year, her troop sold 20 short-sleeved shirts and 25 long-sleeved
shirts. This year, her troop sold 35 short-sleeved shirts and 50 long-sleeved shirts. Which
year's sales had a greater ratio of short-sleeved shirts to long-sleeved shirts?
