The correct answer is A here is the math
Answer: The things that we know in this problem are:
"the number of postcards is 12 more than 3/4 of the number of stamps"
This means that if P is the number of postcards, and S the number of stamps, then:
P - (3/4)S = 12
And we also know that P = 39
39 - (3/4)S = 12
(3/4)S =39 - 12 = 27
S = (4/3)*27 = 36
So he has 36 stamps.
then the correct answer is A.
