b.6x+10y>=120 (5,9),(10,6),and(15,3)are three possible solutions.

c.6x-10y<120 (5,5),(10,10),and(15,15)are three possible solutions.

d.7x+5y<=140 (7,21),(14,14),and(21,7)are three possible solutions.

her goal is to make at least $120 at least meaning is not less than 120, so the mathematical symbol is greater than or equal to >=. so the possible solution is let x be number of bracelety be the number of necklace6x + 10y >= 120 (5,9),(10,6),and(15,3)are three possible solutions.
