Mary is selling her craft to earn money she sells her bracelets for $6 and her necklaces for $10 her goal is to make at least $120 in sales which of the following represents three possible solutions to the problem

a.6x+10y< 120 (5,,5),and(15,0)are three possible solutions.

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

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

d.7x+5y< =140 (7,,14),and(21,7)are three possible solutions.
i think it's
a.6x+10y< 120 (5,,5),and(15,0)are three possible solutions. correct me if i'm wrong.
i think it's between b and
d. is it d

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.

8 and 9, since square root of 64 is 8 and square root of 81 is 9, it is known that square root of 75 is between 8 and 9
