Question

Bridget Creel is getting ready to open a small restaurant. She is on a tight budget and must choose between the following long-distance phone plans Plan A: Pay 9 cents per minute of long-distance calling. Plan B: Pay a fixed monthly fee of $15 for up to 300 long-distance minutes and 7 cents per minute thereafter (if she uses fewer than 300 minutes in any month, she still pays $15 for the month). Plan C Pay a fixed monthly fee of $24 for up to 440 long-distance minutes and 6 cents per minute thereafter (if she uses fewer than 440 minutes, she still pays $24 for the month). Read the requirements. Requirement 1. Match the graphs to the total monthly costs of the three plans for different levels of monthly long-distance calling Before we match the graphs to the plans, complete the following table, calculating the total costs for each plan at each of the different minute levels. (Round to the nearest cent.) Plan 100 minutes 300 minutes 500 minutes

Answer 1

Answer:

attached graphs as answer to first question.

at 100 minutes

9 dollars // 15 dollars // 24 dollars

at 300 minutes

27 dollars // 15 dollars //24 dollars

at 500 minutes

45 dollars // 29 dollars // 27.6 dollars

Explanation:

Plan A is a complete variable plan so no use means a bill of zero dollar. from there, the cost increase by 9 cents per minute

Plan B flat $15 for 300 minutes and increase for 7 cent threafter so we have a line parallel o X-axis up to 300 minutes.

Plan C flat 24 dollars and then 6 cents per minute

Cost at given ranges:

at 100 minutes:

100 x 9 cents = 9 dollars

the other will pay the flat fee

at 300 minutes

300 x 9 cents = 27

the other will pay the flat fee

at 500 minutes

500 x 9 cents = 45

$15 + 200 x 7 cents = 29

$24 + 60 x 6 cents = 27.6
