To solve the inequality, we start by considering the total amount of money \( m \) that the family brings to the amusement park. They need to have at least $21 left after paying a $5 parking fee.
- They pay a $5 parking fee, which means the amount left after paying the fee is \( m - 5 \).
- We want this amount to be at least $21, so we set up the inequality:
\[ m - 5 \geq 21 \]
- Next, we solve for \( m \) by adding 5 to both sides of the inequality:
\[ m \geq 21 + 5 \]
\[ m \geq 26 \]
Thus, the correct response is:
m ≥ 26 (m greater-than-or-equal-to 26)
