To determine the number of hours \( h \) that Moira needs to read to finish the book, you can set up the equation as follows:
\[ 178 + h = 214 \]
Here, 178 represents the hours she has already read, and 214 is the total number of hours needed to finish the book. You can then solve for \( h \) by isolating it on one side of the equation:
\[ h = 214 - 178 \]
When you calculate this, you'll find that:
\[ h = 36 \]
So, Moira needs to read 36 more hours to finish the book.
