Solutions for Week 4 of Recitation/Week 5 of classes
Question 1: Why did you choose to do the alternate assignment instead of attending recitation?
(It’s not required to attend, and you can get full points by completing this assignment, I’m just
curious.)
(Opinion based)
Question 2: True or False. When creating a budget, it only really matters that you include the
biggest expenses like rent, utilities, and gas. Explain your reasoning behind choosing your
answer.
False. When creating a budget, all the components and aspects matter, including the expenses
that take up only a small fraction of the budget. Despite being a small area of the budget, other
expenses such as clothing, food, and online streaming services can eventually add up in the
near future that can eventually sum up to the expense of the biggest expenses. Thus, when
creating a budget, all expenses that you make matter.
Question 3: Suppose you get a $5 footlong (assume 6% sales tax) from Subway for lunch once
a week for a month and you also pay $8/month for Netflix. Calculate your monthly Subway
expense and determine what percentage the Subway expense is of your monthly Netflix
expense. Be sure to show your work or explain your steps. (assume 1 month = 4 weeks)
One footlong =
Since, we buy 1 footlong once a week for one, we’ll use conversion factors to solve for the
amount of money we pay at Subway in a given month:
So, we pay $21.20 per month for Subway sandwiches.
For Netflix, one month of subscription is worth $8.
Thus, we can now find the percentage of the Subway expense if of the monthly Netflix expense.
The following formula is used:
We solve for x:

Thus, the Subway expense is 265% of the monthly Netflix expense.
Question 4: If every month for 2 years you accumulate about $80 in credit card debt with a card
company that has a 13% annual interest rate, when you go to pay off the card at the end of the
second year, how much will you owe? (Round to the nearest cent) Show or explain your work.
First, we find the amount of credit card debt that we would have in a year:
We have $960 in credit card debt in a year. Now, we can calculate the amount after the first
year, using the annual interest rate:
Next, we add the $960 annual debt to our amount and calculate the amount again using the
annual interest rate:
You will owe $2.310.62 at the end of the second year
Question 5: From Q4, how much of what you owe the end of the 2 years is interest? (express
as a dollar amount AND as a percentage). The percentage is not 13% the annual interest rate,
why?
Let’s calculate the interest from the two years:
Year 1:
Year 2:
Now, let’s add these values and divide them by the total debt after two years:
