Answer:
let the total no of articles be n
the value of one article be a
given:
na=900
a=900/n
Step-by-step explanation:
(n-5)*(y+2)=980
na-5a+2n=990
900-5(900/n)+2n=990
2n-4500/n=90
n-2250/n=45
n2-45n-2250=0
n2-75n+30n-2250=0
n(n-75)+30(n-75)
(n+30)(n-75)
n=-30 n=75
since the no of articles cannot be in negative
therefore the no of articles is 75
