I think it’s 5. I’m not sure
Answer:
$13.50 typical tip
Step-by-step explanation:
So to find the percentage
multiply 0.15*90
You’ll get 13.5
Since there are 120 payment and the total interest paid was
$ 14,644.95. so the average monthly interest can be calculated by:
Average monthly interest = $ 14,644.95 / 120
Average monthly interest = $ 122.04
% total interest = ($ 14,644.95) / $ 39,644.95 x 100
% total interest =36.94 %
or 
divide both sides by 2
sinΘ = - 
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ =
(
) =
related acute angle
Θ = ( π +
) = 
or Θ = ( 2π -
) =
