A reasonable estimate would be an estimate of 2.5 feet.
First, Jane must know the volume of the box.
Volume = l * w * h
Volume = 1 * 0.5 * 0.5
Volume = 0.25 yard^3
1 yard^3 = $25
So,
1 : 25 = 0.25 : x
x = 25 * 0.25
x = $6.25
So she need to spend $6.25
Relations are ordered pair sets (x,y) mapping a value to another value
the set of 1st components is called the domain
the set of 2nd components is called the range
