Mrs. Johnson put 22,250 miles
Viefleur [7K]

The change in quantities can be represented as percentage

<em>The percentage decrease in miles driven is 34.83%</em>

The given parameters are:

\mathbf{Initial = 22250}

\mathbf{Final = 14500}

The percentage decrease is calculated as:

\mathbf{\%Decrease = \frac{Final - Initial}{Initial} \times 100\%}

Substitute known values

\mathbf{\%Decrease = \frac{14500- 22250}{22250} \times 100\%}

\mathbf{\%Decrease = \frac{-7750}{22250} \times 100\%}

\mathbf{\%Decrease = \frac{-775000}{22250}  \%}

\mathbf{\%Decrease = -34.83 \%}

The negative sign implies that, the change represents a decrement.

Hence, the percentage decrease in miles driven is 34.83%
