8. Bob has a scale drawing of his kitchen with a scale of \( 4 \mathrm{in} .=5 \mathrm{ft} \). If his kitchen is 12.5 feet in width, what is the width on the scale drawing (inches)?

To find the width on the scale drawing, we start by converting Bob's kitchen width from feet to inches using the scale provided. Given that \( 4 \text{ in} = 5 \text{ ft} \), we can set up a proportion to find the corresponding width in inches: 1. First, determine how many inches correspond to 1 foot by dividing 4 inches by 5 feet: \[ \frac{4 \text{ in}}{5 \text{ ft}} = \frac{x \text{ in}}{12.5 \text{ ft}} \] 2. To isolate \( x \), we can cross-multiply and get: \[ x \text{ in} = 12.5 \text{ ft} \times \frac{4 \text{ in}}{5 \text{ ft}} = 12.5 \times \frac{4}{5} \] \[ = 12.5 \times 0.8 = 10 \text{ in} \] Thus, the width on the scale drawing is **10 inches**.
