Lily sold 18 items at the street fair. she sold bracelets for $6 each and necklaces for $5 each for a total of $101. which system of equations can be used to find b, the number of bracelets she sold, and n, the number of necklaces she sold? b + n = 101 6b + 5n = 18 b + n = 101 5b + 6n = 18 b + n = 18 6b + 5n = 101 b + n = 18 5b + 6n = 101
