Solving inequality that shows the amount of money that a family must bring to amusement park so they will have at least $21 to spend after spending a $5 parking fee
Let's assume the amount of money the family needs to bring to the amusement park is x dollars.
After spending $5 for the parking fee, the family will have x - 5 dollars left to spend.
We want to find the minimum value of x that ensures they have at least $21 left to spend.
So, we can write the following inequality:
x - 5 ≥ 21
Adding 5 to both sides of the inequality:
x ≥ 21 + 5
x ≥ 26
Therefore, the family must bring at least $26 to the amusement park to have at least $21 left to spend after paying the parking fee.
