Answer:
Find out the how many does he have after 4 months .
To prove
As given
Adriano loves anime and collects toys from his favorite series.
Each month he gains 4 toys.
if adriano has 3 toys when he starts collecting .
Now Adriano collecting toys in 4 months = 4 × 4
= 16 toys
Total number of toys Adriano collects = Number of toys already Adriano have + Toys collecting in four months
= 3 + 16
= 19
Therefore the number of toys Adriano have after 4 months is 19 .
