To determine the amount of money \( m \) that a family must bring to an amusement park so they will have at least $21 to spend after paying a $5 parking fee, we can set up the following inequality:
- The family brings \( m \) dollars.
- After paying the $5 parking fee, they will have \( m - 5 \) dollars left.
- We want this amount to be at least $21.
So, we set the inequality:
\[ m - 5 \geq 21 \]
Next, we solve for \( m \):
- Add 5 to both sides:
\[ m \geq 21 + 5 \]
\[ m \geq 26 \]
This means the family needs to bring at least $26 to have at least $21 left after paying for parking.
Therefore, the correct response is:
m≥26
m greater-than-or-equal-to 26
