Five worked problems, each carrying grams, the 4-4-9 multipliers, an energy total and a percentage split: the NS105 Unit 3 energy calculation set, done start to finish. Searches like "ns 105 unit 3 assignment example", "ns105 unit 3 sample" and "ns105 unit 3 example" land here.
What a finished NS105 Unit 3 energy calculation set looks like
Every problem is laid out the same way: given, method, working, answer, check. Problem one takes a snack bar with 30 g carbohydrate, 8 g protein and 12 g fat, multiplies by 4, 4 and 9 to reach 120, 32 and 108 kcal, and totals 260. The percentages come to 46, 12 and 42, which sum to one hundred. A later problem totals a day at 250 g, 80 g and 70 g, for 1,950 kcal, and its rounded shares of 51, 16 and 32 sum to 99; the sample says so in a line rather than quietly adjusting one figure. Another converts a cup of cooked rice to grams before any energy is calculated, and the last compares the day's shares with the acceptable ranges.
How a NS105 Unit 3 example is structured
The set opens with a short key: the energy values used per gram of carbohydrate, protein, fat and alcohol, the source they come from, and the rounding rule applied, usually to the nearest whole kilocalorie and whole percent. Problems then run from simplest to most involved, each numbered and each in its own block on the page so a grader can mark them independently. Units travel with every number; a bare 120 never appears. After the set, a paragraph of interpretation reads the day's percentages against the acceptable macronutrient distribution ranges and says in plain terms which share sits near an edge. Where the prompt supplies label values, one problem compares the label's stated energy with the computed figure and explains the small gap through label rounding and the way fiber is counted.

Units attached to every figure
Grams stay grams and kilocalories stay kilocalories on every line, the simplest protection against the ounce-for-gram slip this course warns about.
Percentages that close
Each split is summed. Where rounding leaves 99 or 101, a one-line note says why instead of nudging a number to force the total.
Conversion before calculation
Household measures are turned into grams with a named source before any multiplier is applied, so every energy figure rests on a stated weight.
Alcohol on a line of its own
Where a drink appears, its alcohol grams take the separate multiplier of 7 and stay out of the macronutrient shares unless the prompt says otherwise.
One paragraph of meaning
The set ends by saying what the day's shares show against the ranges, briefly, and without advice about what anyone ought to eat.
Where marks go in NS105 Unit 3
Arithmetic slips are the obvious loss and not the largest. Bigger deductions go to method that cannot be seen: an answer of 1,950 kcal with no line showing where it came from earns little even if correct, because the grader has no way to tell a sound method from a lucky one. Using 9 for protein or 4 for fat happens more often than anyone admits and spreads through every later problem. Percentages calculated from grams rather than from kilocalories are a classic error; a day with equal grams of carbohydrate and fat does not get equal energy from them. Missing units, figures rounded too early, and a day total labeled as a meal total also cost points. The interpretation paragraph loses marks when it slides into telling a reader what to eat.

NS105 Unit 3 questions, answered
Should percentages come from grams or from kilocalories?
Always from kilocalories. Fat supplies more than twice the energy per gram of carbohydrate or protein, so a percentage built on grams understates fat's share of the day badly. Convert each nutrient to kilocalories first, total them, then divide each by the total. Your grader will likely recompute at least one of these, so show the division.
What if my totals do not match the label?
Small gaps are normal. Labels round their figures, some count fiber at a lower energy value, and the grams listed are themselves rounded. Report your computed total, state the label's figure beside it, and explain the difference in a sentence. A large gap is usually a conversion error worth checking before you submit.
Do I round at each step or only at the end?
Carry full figures through the working and round the final answers, unless your instructions say otherwise. Rounding early compounds small errors, and across a whole day it can shift a percentage by a point or more. Many sections state a rule for this in the prompt; if yours does, follow it exactly, even where it differs from this sample.
