Answer:
let the total no of articles be n
let the value of one article be a
given:
na=900
a=900/n
Step-by-step explanation:
(n-5)*(a+2)=980
na-5(900/n)+2n=990
2n-4500/n=90
n-2250/n=45
n2-2250/n=45n
n2-45n-2250=0
n-75n+30n-2250=0
n(n-75)+30(n-75)=0
(n-75)(n+30)
n=75 n=-30
since the no of articles cannot be in negative
therefore,the no of articles is75
