I apologize, you are correct. It would cost Cai $13.50 to send 90 text messages. Thank you for pointing that out.
To find out how much it would cost to send 90 text messages, we need to determine the cost per text message. We can do this by dividing the total cost by the number of text messages.
Given that it cost Cai $1.80 to send 12 text messages, we can set up a proportion to find the cost of 90 text messages:
12 text messages $1.80
----------------- = ------
90 text messages ?
To solve for the cost of 90 text messages, we cross-multiply and then divide:
12 * ? = 90 * $1.80
? = (90 * $1.80) / 12
? = $13.50
Therefore, it would cost Cai $13.50 to send 90 text messages.
