Step-by-step explanation:
27/30 reduced is 9/10

We need to know the density of Marble City, hence we know the density of Pebble City.
MC density = population/area
MC density = 52,348/125
MC density = 418.784 people/miles
From the question, we know that the two cities have the same population density.
PC density = MC density
PC density = 418.784 people/miles
Use the density formula to figure out the dimension of PC
PC density = population/area
418.784 = 85,312/(l × w)
(l × w) = 85,312/418.784
11.8 w = 85,312/418.784
11.8 w = 203.7
w = 203.7/11.8
w = 17.2
The closest value of x is 17 miles
I believe it is 75% because he is selling them for $3 more than what he bought them for and bought them for $4 and 3 is 75% of 4, sorry if i'm wrong
$400 * 0.13 * 3 = $156
answer is <span>C) $156.00 </span>
