Answer 1

Write answers to all of these questions!

Answer 2

A portray organization has desperate that for each one hundred fifteen sq. ft of wall area,one gallon of paint and eight hours of exertions are required. the organization rates $ 18.00 consistent with hour for exertions. Create an utility that helps the consumer to flow into the style of rooms to be painted and the cost of the paint consistent with gallon. the utility would desire to apply enter packing boxes to ask the consumer for the sq. ft of wall area in each and each room. it would then demonstrate here counsel: . The form of gallon of paint required . The hours of exertions required . the cost of paint . The exertions rates . the entire value of the paint activity Invalid enter: do not settle for a value under a million for the style of rooms. do not settle for a value under $ 10.00 for the cost of paint . do not settle for a damaging fee for sq. photos of wall area.
