Answer:
Step-by-step explanation:
x = 15 cent stamps
y = 20 cent stamps
I will be using these equations
x + y = 16
0.15x + 0.20y = 3
x = 16 - y
0.15(16 - y) + 0.20y = 3
2.40 - 0.15y + 0.20y = 3
-0.15y + 0.20y = 3 - 2.40
0.05y = 0.60
y = 0.60/0.05
y = 12.......there were 12 twenty cent stamps
x + y = 16
x + 12 = 16
x = 16 - 12
x = 4.....there were 4 fifteen cent stamps
no change is received
