cartera Posted December 13, 2008 Share Posted December 13, 2008 The owner must pick between paint A, which costs $6.00 per litre, and paint B, which costs $4.50 per litre. Paint B takes one-third longer to apply than paint A. If the home owner must pay the cost of labour at the rate of $ 36 per hour, 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 libres of paint and 100 hours of labour.
