We will traduce the sentences into equations.
Let x be the number of hours in the first job, and y be the number of hours in the second job.
Then the equations are:

The above system has many solution, we can select for example:
x = 1, y = 16. So we can work one hour at the first job and 16 hour at the second job.
Answer:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:
A = 200(1 + (0.055 × 0.5)) = 205.5
A = $205.50
