Question

An amusement park offers an entrance fee discount of 20% to children under 6 years of age and seniors 65 or older. What is the range of ages that receive the 20% discount fee at the park? Use the appropriate interval notation for either a solution set for a conjunction or a disjunction.

Answer 1

[0, 6) ∪ [65, ∞)

Explanation:

Ages under 6 will be in the interval [0, 5], or in the interval [0, 6), as you may wish.

Ages 65 or older will be in the interval [65, ∞).

The union of these two intervals is ...

[0, 6) ∪ [65, ∞)
