George is an artist and wants to showcase his work in an exhibition.

George requires 30 hours to make a sculpture and 15 hours to make a painting. To display at the showcase he needs at least 5 sculptures and 6 paintings to be ready.

Let x represent the number of sculptures, and let y represent the number of paintings. If George has 300 hours left before the exhibition, which inequalities represent the constraints on the number of sculptures and paintings he can display?
