Write a system of inequalities that describes the possible solutions to the problem.Bruce is a retired carpenter who builds patio chairs and dog houses, which he sells at his local flea market. It takes him 6 hours to build a dog house and 5 hours to build a patio chair. Bruce can work no more than 30 hours per week, and he must produce more chairs than dog houses. Write a system of inequalities to describe this situation. Use D for the number of dog houses and P for the number of patio chairs produced in a week.
A. P > D 5P + 6D ? 30 P > 0 D > 0 B. P ? D 5P + 6D < 30 P > 0 D > 0 C. P + D > 0 P + D ? 30 P > 0 D > 0 D. 5P > 6D P + D ? 30 P > 0 D > 0
