Question

Use the fact that $$13$$ inches is approximately the same length as $$33$$ centimeters to find a mathematical model that relates centimeters $$y$$ to inches $$x$$ . Then use the model to find the numbers of centimeters in $$10$$ inches and $$20$$ inches.

$$y= \frac{33}{13}x$$
x=10 inches$$, y= \frac{330}{13}$$=25.38 cm
x=20 inches,$$y= \frac{660}{13}$$=50.77 cm
