Final Answer:
The correct equation is: D) 10 - 1.25h = 41.25

Step-by-step explanation:

Mrs. Hernandez spends 10 minutes delivering mail to the first five houses. After that, it takes her 1.25 minutes for each remaining house. Let
\(h\)represent the number of houses that still need their mail deliveries.

The total time spent delivering mail is the sum of the time spent on the first five houses and the time spent on the remaining houses, which should equal 41.25 minutes:


\[ 10 + 1.25h = 41.25 \]

To determine how many houses still need their mail deliveries, rearrange the equation:


\[ 10 - 1.25h = 41.25 \]

Therefore, the correct equation is
\[ 10 + 1.25h = 41.25 \], which corresponds to option D.
