An earthquake affected people living within 90 miles of its epicenter. The population density for this region is 125 people per square mile. About how many people live in the region affected by the earthquake?

11,250

Step-by-step explanation:

Population density = Number of people / land area

Population density = 125 people per square mile

Number of people = x

Land area = 90 miles

Population density = Number of people / land area

125 = x / 90

Cross product

x = 125 * 90

x = 11,250

About 11,250 people live in the region affected by the earthquake

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
