You work for the Brads Nailer Company which manufactures two types of nailers: a pneumatic model and a cordless model. You have contracted to supply a national retail chain with both pneumatic nailers and cordless nailers; the minimum number of nailers is given below. However, Brads nailer production capability is limited in three departments: production, testing, and packaging. To minimize your costs, you have determined to ship more cordless nailers than pneumatic. (The number of nailers must be a whole number.)

Your answer will be the production hours needed to execute your production plan - rounded to the nearest whole hour.
