To analyze the situation, we need to set up the equation that correctly represents the problem.
From the information provided, we know:
- The trainer needs 5 treats per horse per training session.
- The total number of mints available is 42.
Thus, we can create the equation:
\[ 5h = 42 \]
Here, \( h \) represents the number of horses the trainer can train.
Dividing both sides by 5 gives:
\[ h = \frac{42}{5} \] \[ h = 8.4 \]
Since the number of horses must be a whole number (you can't train a fraction of a horse), \( 8.4 \) is not a viable option.
So, the correct response is:
5h=42, so h=8.4 horses, which is not viable.
