Given the statement:
It cost Joseph $21.90 to send 146 text messages.
Determine how many text messages did he send if he spent $6.45.
Solution:
In order to determine how many text messages did he send if he spent $6.45. we simply need to determine first the unit rate per text message by dividing 21.90 by 146.
= $21.90/146 text messages
= $0.15/message
Now we can divide 6.45 by 0.15 to determine the number of text messages.
= $6.45/$0.15
= 43 text messages
Final answer:
Joseph sent 43 text messages.
