Step-by-step explanation:
the equation of a circle in standard form is
(x - a)² + (y - b)² = r²
where (a, b) are the coordinates of the centre and r is the radius
(x - 8)² + (y + 6)² = 13 is in this form
with centre = (8, - 6) and r = 
Based on the information given the gain or loss percent on the whole transaction is 1%.
<h3>Gain or loss percent:
</h3>
First step is to calculate the profit on the whole transaction
Profit=(8%×8,000)-(6%×8,000)
