+67 You are the editor of your school newspaper. For the next edition, you are writing a story about inflation. You have located the following chart listing various consumer purchases and their costs in 2008 and 2009, as well as the percentage change. Unfortunately, portions of the chart are missing.
Fill in the missing information (shown by [--A--], [--B--], etc) to complete the chart for your story. Round percent answers to the nearest tenth of a percent. Round dollar amount answers to the nearest whole dollar. Enter your answers in the spaces provided below the chart.
[--B--]: $
[--C--]: %
[--D--]: $
[--E--]: %
[--F--]: $
[--G--]: %
[--H--]: $
+23247 A formula that you can use:
Pct. Change as a Decimal = [ 2009 value - 2008 value ] / 20008 value
To find [A]: Pct. Change as a Decimal = [172,700 - 198,100] / 198,100 = -.128 = -12.8%
[C], [E], and [G] are solved like part [A].
To find [B]: 0.012 = [ 2009 value - 20,600 ] / 20,600
(multiply by 20,600): 247.2 = 2009 value - 20,600 ---> 2009 value = $20,847.20
[H] is solved like [B].
To find [D]: 0.288 = [ 6838 - 2008 value ] / 2008 value
(replace 2008 value with x): 0.2888 = [ 6838 - x ] / x
(cross multiply): 0.288x = 6838 - x
(add x): 1.288x = 6838 ---> x = 6838 / 1.288 ---> x = $5309.01
[F] is like [D].
