A transporter wishes to transfer 1000 bags of sugar to a go down. He has two types of lorries to use. FTR with a capacity of 80 bags and a canter with the capacity of 20 bags. The canter has to make at most twice as many trips as the FTR makes. The total number of trips made by both lorries must be less than 30, and the canter has to make more than 10 trips.
(a) Write down all the possible inequalities to represent this information (take trips made by FTR be x and trips made by canter be y)
(b) Represent the information above on the grid provided
(c) If FTR uses Ksh.1800 worth of fuel per trip, while canter uses Ksh.1000 on fuel per trip Estimate the maximum amount that can be spent on fueling the lorries.
