Answer:
114 text messages
Explanation:
First, you set up the equation and let m represent the number of text messages. 0.25m+17=45.50
Then, you solve for m. 0.25m+17=45.50
1. Subtract 17 from both sides. 0.25m=28.50
2. Divide by 0.25 on both sides. m=28.50/0.25
3. Solve. m=114
Finally, your answer is 114 text messages were sent.
