Which store would you go to in order to get the best deal on your sneakers? Explain your reasoning.
Store A. Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.
