The nike store offers the best deal
The saving per shirt is $2.50
Step-by-step explanation:
Here, we want to compare the prices offered in the two stores
In footlocker, you can get 3 shirts for $55.50
The sales per shirt is thus;
55.5/3 = $18.50
For Nike,
5 shirts for $79.99 which is almost $80
So the price per shirt is $80/5 = $16
