Abuilding is 3 ft from a 10-ft fence that
surrounds the property. a worker wants
to wash a window in the building 15 ft
from the ground. he plans to place a
ladder over the fence so it rests against
the building. (see the figure.) he
decides he should place the ladder 9 ft
from the fence for stability. to the
nearest tenth of a foot, how long a
ladder will he need?

2% compounded quarterly is .5% each quarter  (2% ÷ 4) 
So the principal (200) is multiplied by  1.005 ⁸  (8 because there are 8 quarters in 2 years)

200 x 1.005 ⁸ = $208.14 in 2 years (rounded to the nearest penny)

4% over 12 months is 1/3% every month  or .003333
200 x 1.00333²⁴  (24th power since there are 24 months in 2 years) $216.61 in 2 years rounded to the nearest penny.
The monthly scenario is better.
