Question

6. John predicted that gas prices would raise 3.5% in the month of

January. If gas prices actually rose from $2.25 to $2.30, what was his
percent of error? Plzzz answer

Answer 1

37.5%

Explanation:

Given data

Initila Price= $2.25

3.5% of $2.25

=3.5/100* 2.25

=0.035*2.25

=0.07875

Hence the expected new price is

=0.07875+2.25

=$2.33

The expected increase

=2.33-2.25

=$0.08

The actual increase

=2.25-2.30

=$0.05

Hence the error is

% error= Actual -Expected/Expected*100

% error= 0.05-0.08/0.08*100

% error= 0.03/0.08*100

% error=0.375*100

% error=37.5%

Hence the error is 37.5%
