Answer: 8 + 4x = 30
Explanation:
Since the admission fee to a state fair is $8.00 and each ride costs an additional $4.00. This can be represented in an equation as:
= 8 + 4x
where x = number of rides
Since Karen only has $30.00, the inequality that could be used to determine the number of rides, x, Karen can go on will be:
8 + 4x = 30
We can further solve the equation which will be:
8 + 4x = 30
4x = 30 - 8
4x = 22
x = 22/4
x = 5.5
