Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00

Collect Like Terms
Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
Since the cotangent function is defined as
we have that the cotangent equals zero at , because we have
So, the limit simply becomes
