A model of a new campus building is 5 in tall. If 1 in represents 8.5 ft, how tall will the building be? Round your answers to the nearest tenths place.

Answer:

42.5 ft

Step-by-step explanation:

Start with labeling what you know:

1 in = 8.5 ft

The model is 5 in tall.

If 1 in is 8.5 ft and the model is 5 in, you need to multiple 8.5 ft by 5 (the number of inches). See below.

Use a ratio to solve the problem:

[tex]\frac{1 in}{5 in} = \frac{8.5 ft}{x ft} \\x = 5 in * 8.5 ft\\x = 42.5 ft[/tex]
