Mileage cost: \( 150 \times 0.20 = 30 \) dollars.

Total = \( 135 + 30 = 165 \) dollars.

A rectangular field has a length 4 meters more than twice its width. If the area is 104 square meters, what is the width?

Let width = \( w \). Then length = \( 2w + 4 \).

Area: \( w(2w + 4) = 104 \)

Expand: \( 2w^2 + 4w = 104 \)

Divide by 2: \( w^2 + 2w = 52 \)

Bring to standard form: \( w^2 + 2w - 52 = 0 \)

\( w = \frac{-2 \pm \sqrt{2^2 - 4(1)(-52)}}{2} = \frac{-2 \pm \sqrt{4 + 208}}{2} = \frac{-2 \pm \sqrt{212}}{2} \)

\( \sqrt{212} = \sqrt{4 \times 53} = 2\sqrt{53} \approx 2 \times 7.28 = 14.56 \)
