To represent the number of hours Tyrell still needs to volunteer to reach his goal of 26 hours, you can set up the equation like this:
\[ h + 17 = 26 \]
Here, \(h\) represents the number of hours Tyrell still needs to volunteer.
To solve for \(h\), you can rearrange the equation:
- Subtract 17 from both sides:
\[ h = 26 - 17 \]
- Calculate the right side:
\[ h = 9 \]
So, Tyrell still needs to volunteer 9 hours to reach his goal of 26 hours this month.
