Solve an inequality that shows the amount of money (m) but a family must bring to an amusement park so they will have at least $21 to spend after paying a five dollar parking fee
Let x be the amount of money the family brings to the amusement park.
The total amount of money the family has after paying the parking fee is x - 5.
We want to find the minimum amount of money the family needs to bring to the amusement park so they will have at least $21 remaining after paying the parking fee.
So we can write this as:
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 remaining after paying the $5 parking fee.
