To represent the number of hours Tyrell has left to volunteer in order to meet his goal of 26 hours, you can use the following equation:
Let \( h \) represent the number of hours left for Tyrell to volunteer.
The equation can be written as:
\[ h = 26 - 17 \]
This means that Tyrell has \( h \) hours left to volunteer, and he needs to subtract the hours he has already volunteered (17) from his goal (26).
Calculating this gives:
\[ h = 26 - 17 = 9 \]
So, Tyrell has 9 hours left to volunteer for the month to meet his goal.
