SOMEONE PLEASE HELP ME ANSWER ALL THREE!!!

1. You run a school in Florida. Fixed monthly cost is $5,543.00 for rent and utilities, $5,953.00 is spent in salaries and $1,505.00 in insurance. Also every student adds up to $103.00 per month in stationary, food etc. You charge $720.00 per month from every student now.

You are considering moving the school to another neighborhood where the rent and utilities will increase to $11,434.00, salaries to $6,221.00 and insurance to $2,271.00 per month. Variable cost per student will increase up to $179.00 per month. However you can charge $1,024.00 per student. At what point will you be indifferent between your current mode of operation and the new option?

2. A restaurant prepares 200.00 pizza slices and sells them at a rate of $12.00/slice. Expenses for the restaurant include raw material for pizza at $4.00 per slice, $119.00 for monthly rental and monthly insurance of $44.00. Lost sale are taken as $4.00 per unhappy customer. Leftover pizza can be sold for $2.00. The restaurant is open only for 25 days in a month. Today there was a party at nearby office so the demand for pizza went up to 222.00 slices. How much profit could the restaurant earn today?

3. A vendor prepares 100.00 hotdogs every day and sells at $21.00 /piece. For each hot dog, he spends $12.00 in the raw material. Additionally he spends $0.89 for packing each hotdog and monthly $45.00, $19.00, $11.00 as food truck rent, electricity and other expenses respectively. Lost sales are charged at $5.00 per lost sale. Leftover hotdogs can be sold for $3.

On a particular day in June 103.00 people came wanting to buy a hotdog. Determine the vendor's profit for that day? Assume there are 30 days in the month.
