Final answer:
To find out how much it would cost to send 198 text messages, we can set up a proportion using the given information.
Step-by-step explanation:
To find out how much it would cost to send 198 text messages, we can set up a proportion using the given information. We know that Jocelyn spent $5.60 to send 56 text messages, so we can say that the cost per text message is $5.60/56 = $0.10. Now we can use this information to find the cost of sending 198 text messages:
-
- Determine the cost per text message: $5.60/56 = $0.10.
-
- Multiply the cost per text message by the number of text messages: $0.10 * 198 = $19.80.
