z=3x-54 where z in number of movie seen and x is age
no movies
we can say z=0
0=3x-54
54/3=x
x=18 yrs so up to 18 yrs she has not gone to see any movie
b) first movie
means z=1
1=3x-54
3x=54+1=55
x=55/3
x=18 yrs 4 months answer
c)she see movies once in every 4 months
so in a year she see movie =12/4=3 times in year
answer she see movies 3 times in a year
d)
(i) if z=60
60=3x-54
60+54 =3x
3x=114
x=114/3
x=38 yrs
(ii) if z=100
100=3x-54
3x=100+54
3x=154
x=50 yrs 4 months
e) reason in actual it will not so such movie
(i) when a person reach to age of 38 yrs he/she will have lot of social responsibilities
(ii) when a person reach to 50 yrs age , age factor health social responsibilities exist .due to this reasons it may wrong
