Matrix addition – Refinery Oil Distribution
An oil refinery in Terengganu sent 215,500 liters of oil to distributors in Johor, 65,200 liters to Malacca and 130,400 liters to Penang. Another refinery in Kuching sent 195,500 liters, 90,300 and 252,100 liters to the same distributors in the month of January. The next month’s delivery from Terengganu and Kuching to the same distributors are 202,100 , 176,300 and 282,400 ; 190,300 , 305,100 and 408,000 respectively. (i) write the shipments in January and February from the 2 refineries to the distributors in the 3 states as matrices, respectively. (ii) Use matrix addition to find the total amounts sent to the distributors from the refineries.
