Question

One cell phone company offers a plan that cost $29.99 and includes unlimited nights and weekend minutes. Another phone company offers a plan that cost $19.99 and charges $0.35 per minute during nights and weekends. For what number of night and weekend minutes does the second company's plan cost more than the first company's plan

Answer 1

t ≥ 29

Explanation:

Given the following :

Company A:

Cost of plan = $29.99

Night and weekend minutes = unlimited

Company B :

Cost of plan = $19.99

Night and weekend = $0.35 per minute

Let number of night and weekend minute = t

For what number of night and weekend minutes does the second company's plan cost more than the first company's plan

Company A > Company B

(19.99 + 0.35*t) > 29.99

19.99 + 0.35t > 29.99

0.35t > 29.99 - 19.99

0.35t > 10

t > 10/0.35

t > 28.57

28.57 to the nearest whole number = 29

t ≥ 29
