To write the equation for Aaron's total phone bill, we start with the fixed monthly charge and add the cost per text message multiplied by the number of text messages.
The equation can be expressed as:
\[ 48 + 0.25t = 62 \]
Where:
- \(48\) is the monthly service charge,
- \(0.25t\) is the cost for \(t\) text messages,
- \(62\) is the total phone bill.
Now, we can solve for \(t\):
- Subtract \(48\) from both sides to isolate the term with \(t\):
\[ 0.25t = 62 - 48 \] \[ 0.25t = 14 \]
- Divide both sides by \(0.25\) to solve for \(t\):
\[ t = \frac{14}{0.25} \] \[ t = 56 \]
Therefore, Aaron sent 56 text messages this month.
