North American Housing is a builder of two types of modular homes, a rambler and a spilt-level. The rambler requires 400 worker-days of carpentry, 10 worker-days of painting and sells for a profit of $3000. The split-level requires 300 worker-days of carpentry, 20 worker-days of painting and sells for a profit of $4000. North America Housing has available 48,000 worker-days of carpentry and 1600 worker-days of painting. North America Housing must also produce at least twice as many ramblers as split-levels. The builder will choose the number of each type of house it builds in order to maximize its profit.
