Sam operates his own summer lawn-mowing business using a truck and equipment used solely for business purposes. Sam budgets \($10\) per job for variable expenses (gas for his truck and equipment) and \($500\) per month for fixed expenses (insurance and lease payments). Sam expected to have 100 mowing jobs during the month of June but actually had 125.

How much should be reflected in the flexible budget for (1) variable expenses, (2) fixed expenses, and (3) total operating expenses?
