Answer: 
c) $450,000 
Step-by-step explanation: 
The calculation of the cost of the walk-in program is shown below:- 
Cost of the walk-in program = 1 ÷ 4 × Salaries + 1 ÷ 2 × (Rent + Depreciation) + 1 ÷ 5 × (Utilities) 
= 1 ÷ 4 × $1,000,000 + 1 ÷ 2 × ($300,000 + $80000) + 1 ÷ 5 × $50,000 
= $250,000 + $190,000 + $10,000 
= $450,000 
Therefore for computing the cost of the walk-in program we simply applied the above formula.
