CAFÉ KUPE 1

SCENARIO: RECIPE SCALING

You're preparing 3 separate batches of chocolate chip cookies for Café Kupe. Each batch of cookies requires exactly \(2 \frac{1}{2}\) cups of flour. If you decide to double your recipe order to feed a larger guest group, how many total cups of flour will you need?

Fractions Ans: 15 cups

CAFÉ KUPE 2

SCENARIO: PORTION CONTROL

A chef purchases a large 15-pound wholesale bag of white rice. Each batch of gourmet signature garlic rice pilaf requires exactly \(\frac{1}{4}\) of a pound of rice. How many complete full batches can the kitchen cook from this bag?

Unit Fraction Div Ans: 60 batches

CAFÉ KUPE 3

SCENARIO: BULK COSTING

The wholesale cost of ingredients for one bowl of Café Kupe's premium tomato soup is exactly \$1.45. If the chef prepares a large catering pot containing 24 individual bowls of soup, what is the total ingredient cost for the entire pot?

Decimal Operations Ans: $34.80

CAFÉ KUPE 4

SCENARIO: CAPACITY CONVERSIONS

Café Kupe's secret punch recipe requires exactly 3 gallons of cranberry juice, 4 quarts of apple juice, and 8 cups of orange juice. How many total cups of punch will this recipe yield when mixed?

Customary Units Ans: 72 cups

MODEL COMPONENT: DETAILED MATH SOLUTIONS

EXEMPLAR STEP-BY-STEP ANSWER KEY

This pre-filled double-entry solution key demonstrates how to write crystal clear, step-by-step mathematical calculations for your project workbook. Each step outlines the mathematical reasoning.

SOLUTION FOR CARD 1 FLOUR FRACTIONS

Step 1: Find flour for single order (3 batches):
  \(2 \frac{1}{2}\) cups per batch \(\times 3\) batches.
Step 2: Change mixed number to improper fraction:
  \(2 \frac{1}{2} = \frac{5}{2}\) cups.
Step 3: Multiply:
  \(\frac{5}{2} \times \frac{3}{1} = \frac{15}{2} = 7 \frac{1}{2}\) cups.
Step 4: Double the total recipe order:
  \(7 \frac{1}{2} \times 2 = \frac{15}{2} \times 2 = 15\) cups.

Final Answer: 15 cups

SOLUTION FOR CARD 2 RICE DIVISION

Step 1: Divide total rice weight (15 lbs) by batch weight (\(\frac{1}{4}\) lb):
  \(15 \div \frac{1}{4}\).
Step 2: Multiply by reciprocal (Keep, Change, Flip):
  \(15 \times \frac{4}{1} = 60\).
Step 3: Check the answer: 60 batches of rice pilaf at \(\frac{1}{4}\) lb each is:
  \(60 \times \frac{1}{4} = 15\) lbs (accurate).

Final Answer: 60 batches

SOLUTION FOR CARD 3 DECIMAL MULTIPLY

Step 1: Multiply cost per individual bowl (\$1.45) by total bowls (24):
  \(1.45 \times 24\).
Step 2: Set up multi-digit decimal multiplication:
  \(145 \times 24 = 3,480\).
Step 3: Since there are two decimal places in 1.45, place the decimal two spaces to the left in the product:
  \(3,480 \rightarrow 34.80\) dollars.

Final Answer: $34.80

SOLUTION FOR CARD 4 MEASURE CONVERT

Step 1: Convert all liquids to cups:
  • 3 gallons = \(3 \times 16\) cups = 48 cups.
  • 4 quarts = \(4 \times 4\) cups = 16 cups.
  • 8 cups = 8 cups.
Step 2: Sum all conversions:
  \(48 \text{ cups} + 16 \text{ cups} + 8 \text{ cups}\).
Step 3: Add together:
  \(48 + 16 = 64\), then \(64 + 8 = 72\) cups.

Final Answer: 72 cups
