A bag of rice costs Ksh 12,500, a bag of beans costs Ksh 15,200 and a bag of maize costs Ksh 8,750. A school buys 20 bags of rice, 30 bags of beans and 45 bags of maize in a term.

Represent

(a) the cost of each bought as a 3×1 matrix                      (1 mk)

(b) the number of bags of each as a 1×3 matrix                  (1 mk)

(c) Hence calculate the total cost that the school spent in buying the items.     (2 mks)
