Pleasantville x -2%
amity center y +5%
harmony corners z +7%
Population for Pleasantville if x = 30,250

Population for Harmony Corners if z = x-y
If the population of Pleasantville (x) is 30,250 and it decreases by 2%, the new population would be:
New population of Pleasantville = x - (2/100)x
New population of Pleasantville = 30,250 - (2/100) * 30,250

New population of Pleasantville = 29,645
If the population of Amity Center (y) is 7,500 and it increases by 5%, the new population would be:
New population of Amity Center = y + (5/100)y
New population of Amity Center = 7,500 + (5/100) * 7,500
New population of Amity Center = 7,500 + 375
