Lesson 1: Commodity and money markets are represented by the following parameters (Unit Consumption: C = 60 + 0.75Yd
Export: X = 140
Investment: I= 100 + 0.05Y – 50i
Import: IM = 0.15Y
Tax: T = 0.2Y
Actual money supply: MS = 500
Government spending: G = 250
Actual demand for money: MD = 400 + 0, 2Y -100i
a) Write an equation to represent the IS, LM curves, Determine the equilibrium level of income and interest rate.
b) Assume government spending increases by $30 million. Determine the equilibrium level of income and interest rate. Determine the investment retracement level with this policy.
c) Assuming government spending remains the same but the Central Bank increases the money supply by $30 million, how will the equilibrium output and interest rate change?
d) State the comments drawn from the results of points 2 and 3.
e) Now that the government uses both solutions in questions 2 and 3 at the same time, what is the equilibrium level of output and interest rate? How will this affect the economy in the short and long term?
f) Illustrate the results on a graph.

The starr theater, owned by meg vargo, will begin operations in march. the starr will be unique in that it will show only triple features of sequential theme movies. as of march 1, the ledger of starr showed: cash $3,150, land $22,000, buildings (concession stand, projection room, ticket booth, and screen) $10,000, equipment $10,000, accounts payable $7,300, and owner’s capital $37,850. during the month of march, the following events and transactions occurred. mar. 2 rented the three indiana jones movies to be shown for the first 3 weeks of march. the film rental was $3,600; $1,600 was paid in cash and $2,000 will be paid on march 10.3 ordered the lord of the rings movies to be shown the last 10 days of march. it will cost $200 per night.9 received $4,500 cash from admissions.10 paid balance due on indiana jones movies rental and $2,200 on march 1 accounts payable.11 starr theater contracted with adam ladd to operate the concession stand. ladd is to pay 15% of gross concession receipts, payable monthly, for the rental of the concession stand.12 paid advertising expenses $900.20 received $5,100 cash from customers for admissions.20 received the lord of the rings movies and paid the rental fee of $2,000.31 paid salaries of $2,900.31 received statement from adam ladd showing gross receipts from concessions of $6,000 and the balance due to starr theater of $900 ($6,000 × 15%) for march. ladd paid one-half the balance due and will remit the remainder on april 5.31 received $9,200 cash from customers for admissions.1.) enter the beginning balances in the ledger.2.) journalize the march transactions. starr records admission revenue as service revenue, rental of the concession stand as rent revenue, and film rental expense as rent expense. (credit account titles are automatically indented when the amount is entered. do not indent manually. record journal entries in the order presented in the problem. if no entry is required, select "no entry" for the account titles and enter 0 for the amounts.)3.) post the march journal entries to the ledger. (post entries in the order of journal entries presented in the previous question.)
