Twenty times the quotient of a number and 2 is no less than the difference of the number and 18. Solve the inequality you wrote for this problem.

Each month, Phone Company A charges $204 for unlimited talk and text plus an additional $9.50 for each gigabit of data used. Phone Company B charges $36.75 per gigabit of data used and the price includes unlimited talk and text. How many gigabits of data could a person use monthly to make the total cost from Phone Company A more expensive than Phone Company B? Identify the inequality that models this real-world situation, where g represents the number of gigabits.
