How are direct and inverse variations used in everyday life?

Answer 1

Direct and inverse variations are commonly observed in everyday life through relationships between quantities. For example, in direct variation, as the number of hours worked increases, so does the amount of pay earned, illustrating a proportional relationship. Conversely, in inverse variation, the more people sharing a Pizza, the smaller the portion each person receives, demonstrating how one quantity decreases as the other increases. These concepts help us understand and predict outcomes in various situations, from budgeting to cooking and resource allocation.
