Project.
1.Give the amount of water absorbed by each towel in
milliliters:
Viva___________ Bounty___________ Other ___________
Were you right in your predictions about which would absorb

_______________
2.Do this math to figure out how many milliliters of liquid
are absorbed per 25 sq... cm sheet of towel:
Divide cost per 25 sq.... cm sheet (found on DCS 1) by number
of milliliters absorbed by each towel.
Viva costs ___________ per milliliter absorbed.
Bounty costs ___________ per milliliter absorbed .
"Other" costs ___________ per milliliter absorbed.
Were you right in your predictions about which would be the
