Step-by-step explanation:

(f ∘ g)(-2) = f(g(-2)) = f(-2-3) = (-5)² = 25

Answer:

The yearly payroll will cost the employer $538,250.

Step-by-step explanation:

a) Data and Calculations:

Budgeted payroll = $500,000

Social security tax rate = 6.25%

Medicare tax rate = 1.4%

Social security tax = $31,250 ($500,000 * 6.25%)

Medicare tax amount= $7,000 ($500,000 * 1.4%)

Total taxes amount = $38,250

The total yearly payroll cost should be put at $538,250 ($500,000 + 38,250). This means that as the employees pay taxes amounting to $38,20, the employer will also pay matching taxes amounting to $38,250.
