Emily is building a model of her dog house. the height of the actual dog house is 4 feet.

part a

if the scale of the model is 4 inches = 2.5 feet, what would be the height of the model? show and explain all of your work.

part b

if the scale of the model was changed to 6 inches = 1.5 feet, what would be the height of the model? show and explain your work.

Explanation:

Part A

        Set a proportion:

        4 in / 2.5 ft = x / 4 ft

        Multiply both sides by 4 ft and simplify:

        x = 4 ft × 4 in / 2.5 ft = 16 / 2.5 in = 6.4 in

Part B

        Set a proportion:

        6 in / 1.5 ft = x / 4 ft

        Multiply both sides by 4 ft and simplify:

        x = 4 ft × 6 in / 1.5 ft = 24 / 1.5 in = 16 in
