A patient has been brought to the imaging department for a radiograph of his knee. Previously, the patient had a portable knee exam completed in the emergency department using 70 kVp, 2.5 mAs, and a 6:1 grid. In the x-ray room, the exposure will be completed with the image receptor in the bucky tray with a 12:1 grid. What new mAs will be required for the exposure in the department to compensate for the higher ratio grid? (rounded to the nearest hundredths) 

Recall that the National Savings has 2 components, private savings and public savings. The 2 variables that define public savings is government spending (G) and taxes (T). In this context, when the federal government spends more money than it receives in taxes in a given year, it runs a or . Conversely, when the government receives more money in taxes than it spends in a year, it runs a or . If government spending and taxes are equal, it has a  budget. According to the Congressional Budget Office, in 2024, the federal government spent $6.9 trillion, where almost $4.9 trillion was financed by federal revenues. In this context, in 2024 we had a budget . Finally, a country’s ability to pay its debt is measured by ratio. The higher is this ratio, the is the country’s ability to pay its debt.

Assume that the tax rate is 0.2 of national income, the MPC (marginal propensity to consume) out of after-tax income is 0.9, investment is 210, government spending is 240, exports are 150, and imports are 0.2 of after-tax income.  Aggregate expenditure for each level of national income National Income After-tax Income Consumption I + G + X Minus Imports Aggregate Expenditure $900 708 $1,200 $1,500 $1,800 $2,100 Complete the table by showing your work for at least one row of National Income. If you don’t complete the table and if you don’t show your work for all variables for one row of National Income, you won’t get credit, even if your numbers are correct.  What is the equilibrium level of national income for this economy, justify your answer!

This is a file upload question. Write down your solution in a piece of paper, take a picture and upload your file.  IMPORTANT: typed solutions will not be accepted!  During the Trump years (before Covid-19), the unemployment rate for the US was around 4%, hence, we’re experiencing the so-called Natural Rate of Unemployment. Nonetheless, at that time, the government announced that in order to make the US economy to grow more, it was going to increase government spending and cut taxes. Economists argued that these type of actions would lead to a Crowding Out effect. In your words, explain what is crowding out. Use an example or describe the mechanism that connects private investment and interest rates.  Why the government plans were not successful in that specific US economic situation. Draw an AD/AS diagram (remember to label graph and curves) showing the potential impact of these fiscal policies in the economy. What is the effect observed in the economy? Indicate in your graph!
