24 markers for $1.20 has a unit price of 5c per marker. 36 markers for $1.79 has a unit price of 4.97c so brand b is better value.
Let
the length = x
the width = x-23
perimeter = 122 ft
perimeter = 2 ( length + width )
122 = 2 ( x + x-23)
122 = 2x + 2x - 46
122=4x-46
122+46=4x
168=4x
x=168/4
x=42
length=42
width = x -23
= 42-23
= 19
