To find out how much Manuel must sell to have a weekly income of at least $700, we can set up an inequality.

Let's say the amount Manuel sells in a week is represented by "x."

The commission Manuel earns on everything he sells is 3% of what he sells, which is 0.03x.

His total income per week, including the $400 base salary, will then be $400 + 0.03x.

To find out how much he must sell to have a weekly income of at least $700, we can write the following inequality:

$400 + 0.03x ≥ $700

Now, let's solve this inequality to find the minimum amount Manuel must sell:

$400 + 0.03x ≥ $700

Subtract $400 from both sides:

0.03x ≥ $300

Divide both sides by 0.03:

x ≥ $300 / 0.03

Simplifying:

x ≥ $10,000

So, Manuel must sell at least $10,000 worth of products to have a weekly income of at least $700.
