Since your scale is 1ft:1.26cm, a 30-ft tall school would need to have a
![30*1.26=37.8](https://tex.z-dn.net/?f=30%2A1.26%3D37.8)
cm model. Dividing this by how tall each toothpick is, you'll get:
ANSWER: The model would be 6 toothpicks tall.
To find out how many cotton swabs you'll need, we just divide 37.8 by how tall each swab is:
ANSWER: The model would be 5 cotton swabs tall.
Use PEMDAS to solve this so
4000(1.0005) 52 • 15 =
4002 (52) • 15 = 3,121,500
