To determine the number of hours \( h \) that Moira still needs to read in order to finish the book, we can set up the equation based on the information provided.
We know that:
- Total hours needed to finish the book = 214 hours
- Hours read yesterday = 178 hours
- Remaining hours needed = \( h \)
We can express this relationship with the equation:
\[ h + 178 = 214 \]
To find \( h \), we can rearrange the equation:
\[ h = 214 - 178 \]
Now, we can calculate:
\[ h = 36 \]
So, Moira needs to read 36 hours to finish the book. The completed equation is:
\[ h + 178 = 214 \]
