Answer:
PPF : Downward Sloping Straight Line 
Explanation:
PPF is the locus of product combinations that an economy can produce, given resources & technology. 
It is downward sloping : Because of inverse relationship between two goods- if one has to be increased other has to be decreased , because of same resources & technology.
Marginal Opportunity Cost (Slope of PPC): is ratio of a good sacrifised to gain each additional unit of the other good.
 ∆ Good sacrifised / ∆ Good gained
If this ratio is same i.e constant amount of a good is sacrifised to gain an additional amount of the other one , the slope of PPC is constant & it is a straight line 
Eg : Good1    Good2     MOC [∆Good2/∆Good1] 
       0               20             _         
       10             10           -10/10 = -1                  (10-20)/(10-0)
        20              0           -10/10 = -1                   (0-10)(/20-10)
So , same (1) good 2 is sacrifised to attain a good 1 each time. 
However Generally: MOC is increasing , because of assumption that resources are unequally efficient in various goods production - shifting good from efficient to inefficient increases sacrifise each time. This makes PPC usually concave. 
 
        
             
        
        
        
<h3>Betsy’s gross earnings for January period is $1,140
</h3><h3>Betsy’s net pay for January period is $966.79
</h3>
Explanation:
- Betsy Strand’s regular hourly wage rate = $24
- Betsy Strand’s hourly rate for work in excess of 40 hours = $36
- Betsy works during a January pay period = 45 hours.
- Betsy's pay for January period = $24 * 40 + $36 * 5
- Betsy's pay for January period = $1,140
Betsy’s gross earnings for January period is $1,140
- Betsy’s federal income tax withholding = $86
- FICA tax rate  = 7.65%.
- Betsy’s FICA Taxes Payable = $1,140  * (7.65 / 100)
- Betsy’s FICA Taxes Payable = $87.21
- Betsy’s net pay for January period = Gross earnings - Federal income tax withholding - FICA Taxes
- Betsy’s net pay for January period = $1,140 - $86 - $87.21
- Betsy’s net pay for January period = $966.79
Betsy’s net pay for January period is $966.79

Answer:
social loafing
Explanation:
Social loafing refers to a psychological phenomenon where people who participate in teams will not try their best in order to achieve the team's goals because he/she believes that other team members will do it, and they will either solve the problem or perform the required task. That way they will benefit from other people's work. 
This is not something that only happens in businesses, we all have a classmate that doesn't participate in group assignments because he/she knows that the others will complete it and everyone will be graded equally based on the group's performance.
