\bf \begin{array}{ccll} \stackrel{mm}{model}&\stackrel{ft}{actual}\\ \cline{1-2} 3.5&1\\ 150&x \end{array}\implies \cfrac{3.5}{150}=\cfrac{1}{x}\implies x=\cfrac{150\cdot 1}{3.5}\implies x\approx 42.86

The scale factor of the dimensions of two similar wood floors is 4:3. It costs $207 to refinish the smaller wood floor. At that
Crank

Answer:

$276

Step-by-step explanation:

Create a proportion where x is the cost to refinish the larger wood floor:

\frac{4}{3} = \frac{x}{207}

Cross multiply and solve for x:

3x = 828

x = 276

So, to refinish the larger wood floor, it would cost $276
