Betty's bakery bakes white bread and brown bread. the loaves of bread are then stored in a store room that can house only 900 loaves. the loaves are baked during the day, and in the evening they are delivered to convenience stores. at all times, the number of loaves in the store room must be less than or equal to 900. assuming x to be the number of loaves of white bread and y to be the number of loaves of brown bread, how would the problem be represented in the form of inequality?
