Please I need help to solve these exercises, formulas and procedures. Thanks

1. An employer pays $3,000 monthly rent for office space and $1,000 to 12 employees, plus a $10 bonus for each unit of work completed by the employee during the month. In addition, the employer has a profit of $18 per unit of work per employee. Suppose an employee completes 300 units in a month. Calculate your monthly payment. 2. Stefan's school is selling tickets for a choral performance. On the first day of ticket sales, the school sold 3 senior tickets and 1 child ticket, for a total of $38. The school received $52 on the second day for selling 3 senior tickets and 2 child tickets. Find the price of a senior ticket and the price of a child ticket. a. Suppose the supply and demand equations for posters for a graduating class are given by p=1.6q+5.2 (supply) p=-2.4q+18 (demand) where p is the price in dollars and q is the quantity in hundreds. b. Determine the supply and demand if the posters cost $6.00. Prepare the graph of the two equations in the same coordinate system and identify the break-even point and quantity. Prepare a graph of both equations and determine what each region means
