  Mr. Biwott operates two passenger service vehicles along Nakuru- Eldoret route. One is a 16 seater Matatu and the other is 8-seater van. Each vehicle makes one route trip per day and the charges are ksh 250 and ksh 300 per passenger respectively (one way). The matatu uses diesel which costs ksh.48 per litre and the van uses regular petrol which costs ksh.52 per litre. The fuel consumption of the two vehicles is in the ratio of 4:3 respectively.
  a) If the matatu uses 80 litres for the round trip, determine the fuel consumption of the van for the round trip.
  b) Calculate the daily collection for each vehicle.
  c) Determine which vehicle is more profitable (on daily basis) and by how much.
  d) If the price of both types of fuel goes up by 20% determine the percentage change in daily collection.
