Back in Mr. Binder's day, you had to pay for individual text messages. You had to be careful on how many you were sending because the price added up quickly! In July, he sent 40 messages and in August he sent 65. If the total cost of his text messages was $30 for July, how much money was the messages each?f
we have that
The total cost or July was
$30 -------> 40 messages
Find the unit rate
so
divide the total cost by the number of messages
30/40=$0.75 per message
therefore
teh answer is
$0.75 per message
