We have been given that it cost Claire $6 to send 15 text messages. We are asked to find her cost of texting in texts per dollar.

To find Claire's cost of texting in texts per dollar, we will divide number of total texts by total amount spent.

$\text{Cost of texts per dollar}=\frac{\text{Total texts}}{\text{Total amount}}$

$\text{Cost of texts per dollar}=(15)/(6)$

$\text{Cost of texts per dollar}=(3\cdot 5)/(3\cdot 2)$

$\text{Cost of texts per dollar}=(5)/(2)$

Therefore, the cost of Claire's texting is 5 texts per 2 dollars.
