The variable cost to service a customer's location is $19 per month. The company incurs $2,490 each month to maintain its fleet of four service vans and $3,392 each month in salaries.

What is the expected monthly operating income if 190 customers are added? Operating income $ Attempts: 0 of 3 used (c) Mr. Pharoah is exploring options to reduce the annual bookkeeping costs. Option 1: Renegotiate the current contract with the boakkeeping service to pay a flat fee of $10,212 per year plus $1 per customer per month. Option 2: Hire a part-time bookkeeper for $18,428 per year to handle the invoicing and simple accounting. He would need to pay $6,700 per vear to have taxes and year-end financial statements prepared. Compare the current bookkeeping cost with the two options at customer levels of 916,1,936, and 1,972
