Given:
Lamont has purchased 20 trading cards.
He wants to have at least 50 trading cards.
To find:
The inequality for the number of trading cards Lamont needs and solve it.
Solution:
Let x be the number of trading cards Lamont needs.
He has 20 trading cards. So,
Total cards = x + 20
It is given that, he wants to have at least 50 trading cards. It means, total card must be greater than or equal to 50.
[tex]x+20\geq 50[/tex]
Subtract 20 from both sides.
[tex]x+20-20\geq 50-20[/tex]
[tex]x\geq 30[/tex]
Therefore, the required inequality is [tex]x+20\geq 50[/tex] and solution is [tex]x\geq 30[/tex].
The number of trading cards that Lamont needs will be at least 30 trading cards.
From the information given, we are informed that Lamont has purchased 20 trading cards and wants to have at least 50 trading cards.
Therefore, the number that will be needed more will be:
= 50 - 20 = 30
Therefore, he'll need at least 30 more cards.
