Solve an inequality that shows 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.

To solve this inequality, we need to set up an equation.

Let's assume the amount of money the family brings to the amusement park is "m".

After paying a $5 parking fee, they will have $21 to spend. So, the amount of money they will have after paying the parking fee can be represented as "m - 5".

Since they will have at least $21, we can set up the following inequality:

m - 5 ≥ 21

To solve for "m", we can add 5 to both sides of the inequality:

m - 5 + 5 ≥ 21 + 5

Simplifying the equation:

m ≥ 26

Therefore, the family must bring at least $26 to the amusement park in order to have at least $21 remaining after paying the $5 parking fee.
