What a finished MATH-105N Week 5 loan and interest calculations looks like
Numbered calculations with a short written finding under each, and money on every line. Each item separates the four quantities that drive it: the principal borrowed, the rate as published, the period that rate covers, and how many periods the arrangement runs for. A rate given for the year is converted to the period the payment falls in, and that conversion is shown rather than performed in the writer's head. Simple and compound results appear on the same principal so the gap between them is readable. A payment schedule, where the item includes one, is a short table with its first rows and its last rows present. Every item closes on a total: what was borrowed, what was repaid, and the difference named as the cost of borrowing.
How a MATH-105N Week 5 example is structured
Each of the four quantities goes down labeled with its period, because the whole week turns on a rate and a payment falling on the same clock. Simple interest is worked first and worked openly, since it is the baseline every later figure gets read against. Compound interest follows on the same principal, with the number of compounding periods stated and the arithmetic left visible rather than reduced to one formula result. The two totals are then set beside each other and the difference stated in dollars rather than described as larger. Where a schedule is asked for, it is built row by row with the interest portion and the principal portion separated on each line. The closing paragraph reports the full amount repaid across the term and subtracts the original principal, which is the figure the question was really about.
Four quantities, each with its period
Principal, rate, the span the rate covers and the number of spans. Writing the period beside the rate is what stops an annual figure being used on a monthly payment.
Simple worked before compound
The simple result is the baseline the compound one is read against. Items producing only the compound figure leave the comparison row empty even when the arithmetic is right.
The schedule splits every payment
Each row separates what went to interest from what went to the principal. A schedule reporting only the payment amount shows nothing a single multiplication could not.
Total repaid, minus what was borrowed
The closing figure is the cost of the credit itself. It is usually the largest number on the page and the one a borrower actually wants to know.
Cents at the end, not along the way
Intermediate figures stay long. Shortening each row of a schedule to cents drifts, and across a full term that drift shows up as a visibly wrong final total.
Where marks go in MATH-105N Week 5
The deduction that empties this week is a set producing interest figures that never totals what leaves the borrower's hands from first payment to last, since that total is the reason a general education course teaches borrowing at all. Next in weight is a rate quoted for the year and used unchanged on a payment that falls every month, which returns a figure twelve times too large and looks orderly. Compound results built on the wrong number of periods fail the same way. A schedule whose rows never separate interest from principal cannot show the thing a schedule exists to show. Trimming to cents on every row accumulates a visible error by the last one. And a total with no dollar sign loses the labeling row across every item at once.

MATH-105N Week 5 questions, answered
Does a finished item need the formula, or just the numbers?
The formula goes on the page with its symbols defined, and the numbers go in underneath it. Sections score the substitution separately from the result, so a correct total arriving with no formula above it collects fewer points than a wrong total arriving with a complete setup. Defining the symbols also fixes the period, which is where the real difficulty of the week sits.
How is an annual percentage rate handled when payments are monthly?
It is divided by the number of payment periods in the year before anything else happens, and that division appears on the page. The rate and the payment have to be measured on the same clock or every figure after them is wrong by a factor. Items stating the periodic rate on its own line are easier to mark and easier to correct.
Do these items ever go past borrowing into saving?
Frequently, and the arithmetic is the same one read from the other side. A savings account compounding monthly and a loan compounding monthly use identical working; only the direction of the closing sentence changes. Sections including both usually want the pair worked on the same principal so the symmetry is visible, and the finished set writes that comparison out.
