Question from john, a parent:

What is the better price?
If a bag of mulch sells for $6.75 and contains 2.7 cubit feet versus a bag selling for $5.99 and contains 2 cubit feet.
Which is the better value?
Thank You

Hi John,

The second bag costs $\$5.99$ and contains 2 cubic feet so each cubic foot costs $\large \frac{\$5.99}{2} = \$2.995 .$ The first bag bag costs $\$6.75$ and contains 2.7 cubic feet so each cubic foot costs $\large \frac{\$6.75}{2.7} = \$2.50 .$
