To answer this item, we let n be the number of scarves that Rebecca bought because the number is unknown. The total cost would be the sum of the amount paid for n scarves and 2 purses. The equation would then be,
                                     5n + (12)(2) = 39
Simplifying,
                                      5n + 24 = 39

Thus, the answer is letter B.
