Hi,
The total amount is $1,350.
<em /><span><em>So, firstly we'll start off with the easiest one. We know that they bought a cake for </em><em>$250</em><em>. We also know that there were </em><em>50 people </em><em>invited. Appetizers per person cost $2. So we multiply $2 by 50 people. That's $100. They also charge $20 per person for the main course. Now we multiply $20 by 50 people and get $1,000. Now we add $1,000, $250, and $100 to get our total!</em></span>
<span>x² + 6x = -9
</span><span>x² + 6x + 9 = 0

(x + 3)(x + 3) = 0
x = -3
