Answer:
a) unemployment rate = 15
b) unemployment rate = 2.5
Explanation:
unemployed people are those who are willing and available to work and have actively been seeking a job in the past four weeks. This accurately describes the 12 people who are willing, able and looking for work but cannot find jobs. To calculate the unemployment rate in percentage, the following formula is used:

Where:
a) Number of unemployed = 12
Labour force = 80 (number of people over 16 years of age)

b) if 10 of the unemployed people get discouraged and give up looking for work, the number of unemployed becomes 2 persons, (12 - 10 = 2).

Answer:
$4,044
Explanation:
Calculation for how much of the taxes will be credited to the buyer
First step is to divide the annual taxes by the numbers of days in a year
$8,200 / 365 days
= $22.466 per day
Second step
Based on the information given we were told that the Seller's ownership started from January 1- June 29 which gave us 180 days, this means that we would multiply $22.466 per day by 180 days in order to know how much of the taxes will be credited to the buyer
Hence,
Amount credit to the buyer=180 days
x 22.466
Amount credited to buyer= $4,044
Therefore the amount of the taxes that will be credited to the buyer will be $4,044
