A typical cell phone plan has a fixed base fee that includes a certain amount of data and
an overage charge for data use beyond the plan. A cell phone plan charges a base fee of $62
and an overage charge of $30 per gigabyte of data that exceed 2 gigabytes. If C represents
the cost and g represents the total number of gigabytes of data, which equation could
represent this plan when more than 2 gigabytes are used?
