QLT1 Task 1
Mary is going away to college. In order to stay in touch with her family and friends she needs to get a cell phone with a calling plan. At this time Mary isn’t sure what her monthly phone usage is going to be. After consulting with her college friends, she estimates her usage will be between 200 and 900 minutes per month.
A local phone company offers two basic calling plans:
Plan A. offers a package consisting of monthly charge of $50.00 and $0.10 for each minute. Plan B. offer is a monthly fee of $15.00 and $0.18 per minute.

The phone company charges for actual time used for both plans, so if Mary used .75 Min for talk time she would pay for actual time used [(.75) x per minute rate]

Plan A
The cost of plan (Y)
X= phone usage in minutes (this is our variable)
Y=50 + 0.10(x). The cost of plan A (Y) is $50 base charge plus $.10 per each minute (x) represented in a linear equation.

Plan B
X= phone usage in minutes (this is our variable)
Y=15 + .18(x). The cost of plan B (Y) is $15 base charge plus $.18 per each minute (x) represented in a linear equation.

1. Which plan would offer greater savings if Mary’s monthly phone usage was 200 min?
Plan A
Cost of phone plan after using 200 minutes.
Y=50 + .10(x)
X 200
Y=50 + .10(200)
Y=50 + 20
Y=70
Plan A would cost Mary $70 per month after 200 minutes usage

Plan B
Cost of phone plan after using 200 minutes
Y=15 + .18(x)
X 200
Y=15 + .18(200)
Y=15 + 36
Y=51
Plan B Would Cost Mary $51 per month after 200 minutes usage.

Answer: Plan B would be more advantageous for Mary at $51 per month over Plan A at $70 per month after 200 minutes of usage.

2. Which Plan would offer Mary greatest savings if her monthly usage was 900 min?

Cost of phone plan A after using 900 minutes
Y=50+.10(x)
X 900
Y=50+.10(900)
Y=50+90
Y=140
Plan A would cost Mary $140 per month after 900 minutes usage

Cost of phone plan B after using 900 minutes
Y=15+.18(x)
X 900
Y=15+.18(900)
Y=15+162
Y=177
Plan B would cost Mary $177 per month after 900 minutes usage

Answer: Plan A at $140 per month would offer Mary greater savings.

3. After how many minutes of usage the cost for both plans would be equal?
50+ .10(x) =15+ .18(x) move like numbers from one side of the equation to the other with opposite sign.
50-15= .18(x) - .10 (x)
35=.08(x) divide both sides .08 to extract the value of x
437.5=x

Answer: Both plans would cost the same after 437.5 minutes of usage.

Cost of plan A after 437.5 minutes of usage.
Y=50+.10(x)
Y=50+.10(437.5)
Y=50+43.75
Y=93.75

Cost of plan B after 437.5 minutes of usage.
Y=15+.18(x)
Y=15+.18(437.5)
Y=15+78.75
Y=93.75

Graphical depiction of the above situation.

Plan A Plan B
X y x y
0 50 0 15 200 70 200 51 437.5 93.75 437.5 93.75 900 140 900 177

Plan B would be most advantageous if Mary’s calling time remains under 437.5 minutes per month at which point the monthly cost for both plans is the same. However, if she exceeded 437.5 minutes per month Plan A would make more sense since the cost of plan B drastically increases with additional time over 437.5 minutes.

...Mike Henkle QLT1 Task 5 Western Governors University A. Create a story problem using one of the above real-world scenarios as a basis, including realistic numeric values, by doing the following: 1. Describe the real-world problem. I was looking into phone plans and stumbled upon T-Mobile, and I decided that I needed a cell-phone and took a look at the plans. T-mobile had one plan that was 50 dollars a month and is unlimited talk, text and web, T-Mobile also has a plan for 30 dollars a month for 1,500 talk and text minutes. After you go through your allotted 1,500 talk and text time was up, the cost skyrockets up to 10 cents a minute. 10 cents a minute comes out to 6.00 per hour, I thought in my head. I decided that instead of jumping into a decision about phone plans, that I should first go home and do the math. I wanted to figure out which plan was going to be the most cost effective, and which plan would suite my needs the best. 2. Explain all needs (e.g., financial, non-financial, situational) of the hypothetical consumer. The needs include many different factors: • The first and most important factor how much do you use your phone? The breaking point on the problem today is 200 talk or text above the 1500 minute plan and I will be paying less up front but more on the back end which is no good. If I chose the 1500 minute plan, I will not want to be going over the 1500 minutes as then the cost would go up to 10 cents...
