1. A company won a contract to supply circuit boards. It will produce 1800 circuit boards in the first month and in subsequent months increase this amount by 220 each month. 2. How many circuit boards will be produced in the eighth month? 3. Show that 45220 circuit boards will be produced in total during the first 14 months. 4. The number of circuit boards produced in the first month is actually 2200. If the number of circuit boards produced in subsequent months increases by p each month instead of 220, find the value of p such that a total of 53550 circuit boards are produced during the first 14 months
