Instructions:Select the correct answer.

Answer 1

The correct answer is A here is the math
12+ (3/4x) = 393/4x = 39 -12(4/3)(3/4) = 27 (4/3)x = 36

Answer 2

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.
