. Fungsi Tujuan: Meminimumkan

\mathrm{C}=3 \times 1+4 \times 2

\newline

Fungsi Batasan :

1

).

2 X 1+X 2 \geq 6.000

\newline

2

).

X 1+3 x 2 \geq 9.000

\newline

x 1 \geq 0, x 2 \geq 0

Find Ratio: First, we need to find the ratio of the drawing width to the actual width. $\newline$ So we do $5$ inches (drawing) / $20$ feet (real life).
Simplify Ratio: Next, we simplify the ratio. Since $5$ divided by $20$ is $1/4$ , the ratio is $1$ inch to $4$ feet.
Calculate Scale: So, the scale of the drawing is $1$ inch : $4$ feet.
