Answer:
It should be 128 inches or 10.67 feet tall
Explanation:
Real size of the monument = 160 feet tall
Scale used by Tonya = 4 inches equal to 5 feet
Scale model of the monument = Real size of the monument / Scale used
Proportion between real monument and scale model = 160 / 5 = 32
It means that the proportion between the real monument and the scale model is 32
Scale model height = Proportion * scale used
Scale model height = 32 * 4
Scale model height = 128 inches
Scale model height = 128/12 = 10.67 feet (12 inches = 1 feet)
