a home owner must pick between paint A which costs \$6.00 per liter, and paint B, which costs \$4.50 per liter. Paint B takes one-third longer to apply than paint A. If the home owner must pay labor costs, which of the two paints will be cheaper to apply?

1. The ratio of the area covered by one liter of paint A to the area covered by paint B is 4:3.

2. Paint A will require 40 liters of paint and 100 hours of labor.

The answer given is E. [/u]

i guess answer is E coz we know nothing about labour costs... they could be a fixed cost -say 100\$ for painting the whole area- or variable -say 1\$ per hour, or 1\$ per inch painted or whatever-...
