Meaning of the equation.
(a):
Explanation of Solution
Consumption spending: Consumption spending refers to the amount of expenditure incurred for consuming goods and services at a particular tie period with the given level of income.
Investment: An investment is the money invested in terms of assets and buildings by the individual, for future consumption and profit making.
GDP (Gross domestic product): GDP refers to the market value of all final goods and services produced in an economy during an accounting year.
Multiplier: Multiplier refers to the ratio of change in the real GDP to the change in initial consumption at a constant price rate. A multiplier is positively related to the marginal propensity to consume and negatively related with the marginal propensity to save.
Marginal propensity to consume (MPC): Marginal propensity to consume refers to the sensitivity of change in the consumption level, due to the changes that have occurred in the income level.
(b):
Marginal propensity to consume.
(b):
Explanation of Solution
The slope of the consumption function is the marginal propensity to consume (MPC). Since the consumption function is

(c):
Compare with full employmnet level.
(c):
Explanation of Solution
Since the interest rate r is 4 percent, the GDP can be equated as follows:
The GDP is 1800. The calculated GDP

(d):
Impact of change in government purchase.
(d):
Explanation of Solution
Assuming no change in
Since the MPC is 0.75, the multiplier can be calculated thus
The multiplier is 4. Thus, to increase GDP by 200

(e):
Change in interest rate to bring the economy back to full employment level.
(e):
Explanation of Solution
Assuming no change in fiscal policy, a decrease in interest rate would restore full employment. The amount at which the interest rate needs to be decreased can be calculated as follows:
The interest rate needs to be 3 percent for full employment. Thus, a decrease of 1 percent

They should analyze competitors' prices and customer sensitivity to price changes, determine price elasticity, and test the strategy by implementing a slight price increase and monitoring sales closely. If costs exceed revenues, the couple should analyze their financials, evaluate their business model, explore new revenue streams, and consider long-term viability. They should analyze their financial statements to identify high costs and areas for reduction, evaluate their business model based on market demand, and explore new revenue streams like catering, special events, or partnerships with local businesses. Long-term viability is a key consideration, as if the business still operates at a loss after making adjustments, it may be necessary to consider shutting down. Staying in business should be…arrow_forward
- Respond to following post. You can charge higher prices if the parents think these are valuable by providing different services such as extended hours, healthy lunches, and smaller staff-to-child ratios. But pushing for prices much higher won’t make sense unless parents think the added value is worth the price hike. You should research your local parents to find out what they want. If you want your business to be profitable, then focus on your strengths, do great work and have a reputation. Promote your special products and keep your prices low. If you want to see if you’re making money, keep a log of all your profits and losses. You’re making money if you’re earning more than you’re losing. A break-even analysis can help you figure out how many customers you need to eat and start making money.
