well, let's see
Belk
$25 for 2 shirts, that means 1 shirt is 25 ÷ 2, or $12.5.
Old Navy
$45 for 4 shirts, that means 1 shirt is 45 ÷ 4, or $11.25.
Target
$30 for 3 shirts, that means 30 ÷ 3 for 1 so, 10 bucks each.
Gap
$55 for 6 shirts, meaning 55 ÷ 6 for 1, or about $9.17.
which one is the cheapest? yeap, you're correct.
