The California Department of Transportation (CalTrans) is preparing a flexible budget for its new "Express Lanes" program in District 7. Using their Fastrak transponder, drivers can travel in the carpool-restricted HOV lanes at any hour of the day by paying an extra fee.

CalTrans wants to prepare flexible budget for three levels of usage volume: "Low", "Medium" and "High". Annual revenue and cost data for each of the usage scenarios is presented in the table below.
