 B. contractionary fiscal policy
Explanation:
The government influences economic direction through fiscal policy measures of increasing or decreasing its expenditure and taxation. Therefore, fiscal policies involve the government's actions of adjusting its spending and taxation to achieve desired economic objectives. 
Fiscal policies can either be contractionary or expansionary. Contractionary measures are applied to control rising inflation and moderate the rate of growth. These policies aim at reducing liquidity in the market, thereby achieving stable prices. A reduction in government spending and an increase in taxation reduces liquidity or money circulation.

C. Yes. If repair rates are higher for planes that have been resold, this would be an indication of a lemons problem
Explanation:
Lemons problem is an issue of quality of product, asset, investment : due to asymetric information about the respective quality. 
Asymetric Information is when one one party in transaction has more knowledge about the quality of product or asset, than the other party. 
Second hand goods are an illustration of this case, as seller has more information about the real quality of good or asset than buyer. 
Lemon's problem in single engines airplanes : can be analysed by concept of second hand goods 'asymetric information, lemons problem' it. If the 2nd hand resold planes require higher repairs, it indicates that the buyer had asymetric information about bad quality of planes ( the information which seller had), but realisation of bad quality later implies higher repairs. 
 
        
             
        
        
        
Answer:
make an adjusting entry to debit Interest Receivable and to credit Interest Revenue for the amount of interest accrued since the last interest receipt date.
Explanation:
Adjusting entries are used at the end of an accounting period to assign income and expenses that has accrued.
In this instance when the interest reciept day comes after accounting period we need to recognise the amount of interest earned so far.
The amount accrued since last interest payment date is calculated.
This amount has been earned so it should be recognised as revenue. To do this we debit interest receivable and credit interest revenue.
 
        
             
        
        
        
Answer:
$43
Explanation:
The total cost incurred by the company is made of two classes of cost namely; Fixed and variable cost. While the fixed cost is constant, the variable cost is dependent on the number of tractors produced.
A such,
Fixed cost = $550,000
Variable cost = 22000 × $180 = $396,000
Total cost = $550,000 + $396,000
= $946,000
The average cost per tractor is the result of the ratio of the total cost to the number of tractors
average cost per tractor =  $946,000/22,000
                                          = $43
