The inequality: 2.5v + 20 ≥ 40
v ≥ 8
Explanation:
Rewards for signing up = 20
let the number of visits = v
rate = 2.5 points per visit
Amount needed for a free movie ticket is atleast 40 points
Atleast 40 is reperesented as ≥ 40
Rewards for signing up + rate (number of visits) ≥ 40
20 + 2.5(v) ≥ 40
The inequality:
2.5v + 20 ≥ 40
Solving the inequality:
2.5v + 20 - 20 ≥ 40 - 20
2.5v ≥ 20
v ≥ 20/2.5
v ≥ 8
