Need help working this problem out, any assistance is appreciated.
A dance studio measures 150 feet by 120 feet. A scale drawing of the dance studio floor measures 10 units by 8 units. What scale was used to create the scale drawing?
A) 1 unit: 8 feet
B) 1 unit: 10 feet
C) 1 unit: 15 feet
D) 1 unit: 20 feet
Since 10 times 15 is 150 and 8x15=120 we see that each unit is 15 feet.
