The basic plan for your cell phone is $ 29.99 each month. The cost of regular phone service with unlimited long distance is $ 39.99. Define a variable and write an inequality that will help you find the number of long-distance call minutes you may make and still save money.
The number of long-distance call minutes, an inequality and also define a variable.
Answer to Problem 18P
The number of long distance call minutes are 200.
Inequality is given below;
Explanation of Solution
Given:
Long distance call cost $0.05 per minute.
The basic plan is $29.99.
Cost of regular phone services with unlimited long distance is $39.9.
Let number of long-distance call minute is x.
So, for x minutes, total cost per months:
Since, unlimited long-distance plan price = $39.99.
For being in profit (to save money with basic plan):
Hence, x is number of minutes of long-distance call.
