Answer:600 messages
Step-by-step explanation: For every dollar, there are 100 cents. 100 cents divided by 5 = 20. This means 20 messages per dollar. Since it was only one month, $30 dollars was payed through the amount of messages she sent. Therefore, 20*30 = 600 messages.
it’s 600 because 60 is the total and heather pays 30 monthly. so 60-30 is 30. then 30 divided by 0.05, which is 600 so that’s the answer
