Answer 1

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.

$x+20\geq 50$

Subtract 20 from both sides.

$x+20-20\geq 50-20$

$x\geq 30$

Therefore, the required inequality is $x+20\geq 50$ and solution is $x\geq 30$.
