Answer 1

Answer:

6 7/8 inches

Step-by-step explanation:

The first thing to do is to get the measurements in either inches or feet.  You can't have both.  Let's go from feet to inches.

3 feet = 36 inches

13.75 feet = 165 inches

Now we can set up a proportion to solve for the number of inches the model is:

$\frac{model}{real}:\frac{1.5}{36}  =\frac{x}{165}$

Now we can cross multiply:

36x = 247.5 so

x = 6.875 or 6 7/8 inches
