Answer: A. $1.42
Explanation:
-Postcards = P
-large envelope = E
14p + 5e = 12 or 5e = 12 -14 p
10p + 15e = 24.8
5e = 12 - 14 p multiply by 3
15e = 36- 42 p
Combine 10p + 15e = 24.8 and 15e = 36- 42 p
That equals 10p + 36 - 42p = 24.8
10p + 36 - 42p = 24.8
11.2 = 32 p
P = 0.35
Bring down the equation 5e = 12 - 14p and substitute
5e = 12 - 14p
5e = 12 - (14 x 0.35)
5e = 12 - 4.90
5e = 7.10
e = 1.42
