I'm stuck on this math problem: Geordie takes a toll road on his drive to work and back every day of his five-day workweek. The toll is $12.50 per car or $7 per motorcycle. Both his car and his motorcycle get 35 miles per gallon of gas and the commute to work is 14 miles. Gas costs him $3.75 per gallon. Geordie drives his car to work three times a week and his motorcycle to work twice a week. How many dollars does he spend driving to work and back on the same route in a week?
Can you help?
