Answer:
If it cost Hudson $28.20 to send 188 text messages, it would cost $9.45 to send 65 text messages. So the answer would be $9.45.
Explanation:
Let me explain why. The answer is 9.45 because, 28.20 divided by 188 is 0.15. Then, if you multiply 0.15 by 63 you get 9.45.
28.20/188=.15
.15x63=9.45
So yeah, that's why if it cost Hudson $28.20 for 188 messages, it would be $9.45 to send 65 messages. So again, the answer is 9.45. I hope this was helpful and makes you understand it more now. :D
