Answer:
t ≥ 29
Step-by-step 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
