To answer this item, we let x and y be the number of pair of skis and skates, respectively. The equations that would best represent the given situation are,
                                       40x + 50y = 600
                                          x + y = 13
The values of x and y from the equation above are 5 and 8, respectively. Thus, the school bought 8 pairs of skates.
