Answer 1

$1220

$500 + $0.3x

Explanation:

First of all, Ana makes a guaranteed $500. We set that aside, like a constant.

Now, we proceed. We're old she earns 30% extra on her total sales for the week. This means her earnings will be.

$500 + 0.3x, where x is her total sales for the week. Thus, in a week she made $2400 sales, she'd earn

$500 + 0.3 * 2400

$500 + $720

$1220

That means, she earns $1220 in that week
