Answer:
15 49-cent stamps
Step-by-step explanation:
We can solve this problem with the equations <em>0.49(x) + 0.21(y) = 9.45 </em>and <em>x - 5 = y</em>. Well, 0.49(15) + 0.21(10) = 9.45, so we know that there are 15 49-cent stamps and 10 21-cent stamps. The question is asking for the number of 49-cent stamps, so we can tell Travis bought 15 49-cent stamps.
