The situation described above forms an arithmetic series with first term (a1) equal to 22 and common difference (d) equal to 3. The sum of the first 10 terms is calculated by,
Sn = (n/2) x (2a1 + (n - 1) x d))
Substituting,
S10 = (10/2) x (2 x 22 + (10 - 1) x 3))
The value is 355. Therefore, the answer is letter "B. $355"
