feet. Then 6*4=24 So the answer is C
7. 1200 m/8 cm = C. 1 cm = 150 m
8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.
B. A=lxw so 16*12= 216

Hope that helps

Answer:
18000$
Step-by-step explanation:
Frim the text you have the formula:
V=c-crt
where,
c=30000
r=0.1
t=4
So, new value after 4y:
V=30000-4*0,1*30000=30000-12000=18000
