Question 51374This question is from textbook college algebra
: I got stuck on this word problem can anyone help, thanks.
At the Northside assembly plant, 5% of the workers were classified as minority, while at the southside assembly plant, 80% of the workers were classified as minority. When Northside and southside were closed, all workers transferred to the new Eastside plant to make up its entire work force. If 50% of the 1500 employees at Eastside are minority, then how many employees did Northside and Southside have originally??

When Northside and southside were closed, all workers transferred to the new Eastside plant to make up its entire work force. If 50% of the 1500 employees at Eastside are minority, then how many employees did Northside(N SAY) and Southside(S SAY) have originally??
MINORITIES IN N.S PLANT = 5%..THAT IS N*5/100=N/20.....................1
MINORITIES IN S.S.PLANT = 80%...THAT IS S*80/100=4S/5.................2
BOTH WENT TO E.S.PLANT
HENCE TOTAL WORKERS = N+S=1500.................3
MINORITIES ARE = 50%.....THAT IS 1500*50/100=750
BUT FROM 1 & 2 ..750 = N/20 + 4S/5
MULTIPLYING BY 20......... N+16S=15000................4
EQN4 - EQN.3
15S=15000-1500=13500
S=900
N=600
