Answer:

$r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}$

Jason sells computer software. He earns a base salary of $2,766.79 per month. In addition, he earns 9% of his total monthly sale

ipn [44]

Let's start with saying he earned 2766.79. He he also earns 9% of his sales.

9% of something is just .09 multiplied by that something. So if he earns 9% of 3743.37 plus the 2766.79, then we can say

y= 0.09 * 3743.37 + 2766.79
y = 3,103.69
