Three students, respectively denoted by P1,P2, and P3 have a choice of two stationers, respectively
denoted by W1 and W2. In the accompanying tables, a shopping list of each of the students and the
respective prices of the required items in each of the shops is given: / Drie student, P1,P2 en P3 woon
naby twee winkels W1 en W2 wat skryfbehoefstes verkoop. In die tabelle hieronder word die inkopielys
van elke student en die prys per eenheid by elke winkel gegee:

Compose appropriate matrices and use matrix multiplication to determine at which one of the two stores
(W1 or W2) each student (P1,P2 and P3) should buy the stationery, to ensure that each student pays as
little as possible? / Stel geskikte matrikse saam en gebruik matriksvermenigvuldiging om te bepaal by
watter een van die twee winkels (W1 of W2) elkeen van die studente (P1,P2 en P3) die skryfbehoeftes
moet aankoop, om te verseker dat elke student so min as moontlik vir die skryfbehoeftes betaal?
