Answer: after 5 months
Step-by-step explanation:
Let x be the number of months it takes for Dalia to have more gems than Grace.
We can set up an inequality; the left side representing Dalia and the right side representing Grace
20x > 120-10x
We can add 10x to both sides:
30x > 120
We can divide both sides by 30:
x > 4
Therefore, after 5 months Dalia will have more gems than Grace.
