Question

How would you solve this word problem in one variable inequality form?
One cell phone company offers a plan that costs $29.99 and includes unlimited night and weekend minutes. Another company offers a plan that costs $19.99 and charges 35 cents per minute during nights weekends. For what numbers of night and weekend minutes does the second company's plan cost more than the first company's plan?
plan1 = 29.99

plan2 =19.99 + .35m

plan2 > plan1
19.99 + .35m > 29.99
.35m > 29.99-19.99
.35m > 10
m > 10/.35
m > 28.6 minutes

it will cost more if you exceed 28 minutes
By how much does +5 exceed -5?
