I need the formula please

A rm produces 500 units of a good which cost an average of ti 10 each to produce and sells the at a price of ti 15. What is its prot? When the price of a product is lowered from tl 150 to II 100 quantity demanded increases frc 500 to 750 units. Calculate the elasticity of demand over this section of its demand schedule. Formula for elasticity of demand: change in quantity l Isl quantity + End quantity) change in price 1111' t' = A Bureau de Change will sell Turkish Lira at an exchange rate of 18.2 tl to the euro and charges a flat rate commission of EUR 2 on all transactions. (i) Write an expression for the number of Turkish Lira that can be bought for EUR at (any giv quantity of EURO), and (ii) evaluate it for x = 300. The basic hourly rate for a weekly paid worker is tl 200 and any hours above 40 are paid at ti 2! Tax is paid at a rate of 15% on any earnings above tl 2500 a week. Assuming hours worked F week (Hi exceed 40, i. write an expression for net weekiy wage in terms of H and then simplify it. ii. if H = 50, how much net pay received by the worker? A good, costs a basic tl 150 a unit but if an order is made for more than 10 units this price reduced by a discount of ti 5 for every one unit increase in the size of an order (up to a maximL of 30 units purchased), i.e. if the order size is 11, price is 145; if it is 12, price is 140 etc. Wr an expression for the total cost of an order in terms of order size and simplify it. A rm has to pay xed costs of ti 5000 and then tl 200 labour plus tl 50 raw materials for each u produced of good X. Write an expression for average cost and simplify. A rm has to pay fixed costs of tl 15000 plus another tl 200 for each unit produced. How mu can it produce for a budget of ti 80000? You sell 200 shares in a company via a stockbroker who charges a at tl 100 commission rate- all transactions under tl 1000. Your bank account is credited with tl 800 from the sale of the sharn What price were your shares sold at
