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

Answer 1

Let x be the amount of money the family brings to the amusement park.

After paying the $5 parking fee, the family will have x - 5 dollars to spend at the park. We want to find the minimum amount of money the family must bring such that they will have at least $21 to spend after paying the parking fee.

So we have the following inequality:
x - 5 ≥ 21

Solving for x:
x ≥ 21 + 5
x ≥ 26

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