Well, you lost the original $100 and then you gained back $70 but gave away $70 worth of merchandise, so it evens out and you lost $100 in total
We analyze the linear function to find that it has equation

. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting 
into the given equation:




Hence,

or

, so there are both positive and negative values for

.
5.99(1.75)= 10.4825
10.4825 to the nearest hundredth is 10.48
$10.48
