96) Kilson Dental Centre currently charges \$20 per dental exam.  A new company that recently located near the dental centre asked if the dental centre would be interested in providing dental services to their employees at a special rate of \$15 per dental exam.

The dentists have agreed to offer the dental exams at the reduced fee if the \$15 would cover the variable costs of the dental exam.
