Answer:
Step-by-step explanation:
if 84 dollars represents ...............20% of his income
?.........represents ...........................100%
84*100/20=420 dollars
We know that
[scale]=[measure in model park]/[measure in actual park]
[measure in model park]=[scale]*[measure in actual park]
scale=1.5 cm/50 m
If the distance between two trees in the park is 150 m
so
[measure in actual park]=150 m
[measure in model park]=[1.5/50]*[150]------> 4.5 cm
the answer is the option
<span>B. 4.5 cm</span>
