Given 20 yards for $30.00, unit rate = $30 / 20 yards = $1.5 per yard

Given 40 yards for $45.00, unit rate = $45 / 40 yards = $1.13 per yard

Given 50 yards for $70.00, unit rate = $70 / 50 yards = $1.4 per yard

Given 65 yards for $85.00, unit rate = $85 / 65 yards = $1.31 per yard

The best deal is the cheapest rate which is 40 yard for $45.00
