Answer:
Option C. 1:11
Step-by-step explanation:
Let
x-----> dollars  spent on office space
y ----> dollars spent  on other costs
we know that
x+y=$360,000 -----> equation A
x=$30,000 ----> equation B
substitute equation B in equation A and solve for y
30,000+y=360,000
y=360,000-30,000=$330,000
Find the ratio of dollars  spent on office space to dollars spent  on other costs
Divide the dollars  spent on office space by the dollars spent  on other costs
so
x/y
substitute
30,000/330,000=1/11
