information below contains the annual earnings (in rands) of a company over a five year period from 2010 to 2015, as well as the Consumer Price Index for the same period:
Year Annual earnings Consumer Price Index Real earnings
2010 13450 100 A
2011 13800 105 B
2012 15000 112 C
2013 16500 123 D
2014 18000 132 E
Find the value of B.
14113
13563
13003
14213
13143
To find the value of B, we first need to calculate the real earnings for each year using the formula:
Real earnings = (Annual earnings / Consumer Price Index) * 100
Using this formula:
A = (13450 / 100) * 100 = 13450
B = (13800 / 105) * 100 = 13142.86 ≈ 13143
C = (15000 / 112) * 100 = 13392.86 ≈ 13393
D = (16500 / 123) * 100 = 13414.63 ≈ 13415
E = (18000 / 132) * 100 = 13636.36 ≈ 13636
Therefore, the value of B is 13143.
