Also every student adds up to $105.00 per month in stationary, food etc. You charge $718.00 per month from every student now. You are considering moving the school to another neighborhood where the rent and utilities will increase to $10,730.00, salaries to $6,707.00 and insurance to $2,272.00 per month. Variable cost per student will increase up to $150.00 per month. However you can charge $1,170.00 per student. At what point will you be indifferent between your current mode of operation and the new option?

Expenses for the restaurant include raw material for pizza at $5.00 per slice, $111.00 as monthly rental and $34.00 monthly as insurance. Restaurant is open only for 25 days in a month.
