the answer is 60 photographs

Step-by-step explanation:

given

let each autobiographies =a

and photography. =b

autobiographies cost =20/-

photographs cost. =50/-

then we can write the equation as (5a+b)

the total cost of autobiography Sun photographs is160/-

5a+b=160

5*20+b=160

100+b=160

b=160-100

b=60.

therefore the family buy 60 photographs.
