What a finished MT421 Unit 4 time value problem set looks like
Four pages, one problem per half page, each laid out the same way: the question in Kayla's terms, an input line, the formula, the calculator or spreadsheet entries, the answer and one sentence of meaning. Problem one grows her $2,400 savings for three years at 4.0 percent compounded monthly, to $2,705. Problem two finds the $256.60 monthly deposit that would lift it to $9,000 in two years. Problem three checks the car loan: $11,300 at 7.4 percent with $318 payments leaves about 40 months and $1,494 of interest. Problem four shows the Visa at a fixed $150 taking 57 months and $3,688 of interest, against 14 months and $851 at $400. Problem five sets a $449 monthly deposit toward $29,770 of cash to close on a condominium in five years. Problem six values the forgone match.
How a MT421 Unit 4 example is structured
Single sums lead, annuities follow, loans come next and one long-horizon sum closes the set, so each problem adds one idea to the last. Inputs appear before any formula in a fixed line, rate per period, periods, present value, payment, future value and timing, letting a reader rerun every answer on any calculator. Compounding is converted explicitly: the 4.0 percent savings rate becomes 0.3333 percent a month, and the card's 26.24 percent becomes 2.187 percent. Payment timing is stated each time, because an annuity due changes the answer. The interpretive sentence after each result ties it to Kayla's next decision, so the card problem ends by noting that raising the payment by $250 saves more than $2,800 of interest. The final problem runs two return rates, 5 and 7 percent, to show how heavily the assumption drives a 38-year result.
One layout, six times
Question, input line, formula, keystrokes, answer and meaning, repeated so every solution can be checked the same way.
Savings, forward and backward
Growth of the current $2,400 and the deposit needed to reach $9,000, both at a stated 4.0 percent compounded monthly.
Two debts, solved for time
Months remaining on the car loan and on the Visa at two payment levels, with total interest beside each answer.
Cash to close in five years
The monthly deposit toward a condominium's down payment and closing costs, previewing the housing decision later in the term.
The match nobody claimed
One year's forgone employer contribution carried to age 67 at 5 and 7 percent, about $3,700 and $7,600.
Where marks go in MT421 Unit 4
Answers without inputs cannot be checked, and in this unit that usually costs more than an arithmetic slip would. A rate converted to the compounding period is something graders commonly check, since a 4 percent annual rate entered as 4 per month produces absurd results. Payment timing, beginning or end of period, has to be stated; silence on it leaves an annuity answer ambiguous. Problems solved correctly but never interpreted miss the course's intent, which is decisions rather than numbers. Rounding intermediate results too early creates small errors that compound across a loan schedule. Textbook problems copied without adapting them to the case receive less credit where the prompt supplies a person with goals. Formula notation and calculator keystrokes are both acceptable in most sections, provided one is shown in full.

MT421 Unit 4 questions, answered
Should I show formulas or calculator keystrokes?
Either, as long as the inputs are visible. Many instructors accept formula notation, financial calculator keystrokes or spreadsheet functions such as PMT and FV. What loses credit is a bare answer. Write the rate per period, number of periods, present value, payment, future value and timing, then show whichever method you used to solve.
Why does compounding frequency matter so much?
Because the rate and the number of periods must match. A loan quoted at 7.4 percent a year with monthly payments uses 7.4 divided by 12 per month and counts periods in months. Mixing an annual rate with monthly periods is one of the most common errors graders see, and it can distort answers badly.
How many decimal places should the answers carry?
Dollar answers round to the cent, and rates to at least four decimal places during calculation. Round only the final answer. Rounding a monthly rate to two places early can move a thirty-year result by hundreds of dollars. If your prompt specifies a rounding rule, follow it and say so.
