The inequality that can be used to determine the number of visits Owen can make to earn his first free movie ticket is:
30 + 12.5x ≥ 115
Where x is the number of visits Owen makes.
To solve for x:
Subtract 30 from both sides of the inequality:
12.5x ≥ 115 - 30
12.5x ≥ 85
Divide both sides of the inequality by 12.5:
x ≥ 85/12.5
x ≥ 6.8
Since the number of visits must be a whole number, Owen can make at least 7 visits to earn his first free movie ticket.
Owen has a points card for a movie theater.
He receives 30 rewards points just for signing up.
He earns 12.5 points for each visit to the movie theater.
He needs at least 115 points for a free movie ticket.
Write and solve an inequality which can be used to determine
x, the number of visits Owen can make to earn his first free movie ticket.
