Answer:If Shamus receives $750.00 per week, then he receives $750.00 x 52 = $<<75052=39000.00>>39,000.00 per year.
His new monthly salary of $3,498.00 is equivalent to $3,498.00 x 12 = $<<349812=41970.00>>41,970.00 per year.
Therefore, Shamus' annual salary increased by $41,970.00 - $39,000.00 = $<<41970-39000=2970.00>>2,970.00.
