Mathematical Formula & Logic
Step-by-Step Worked Calculation
Scenario: Comparing Two Brand Prices
Brand A: 12 oz for $3.60. Brand B: 16 oz for $4.80. Which is the better deal?
Step 1: Calculate Brand A unit rate: $3.60 ÷ 12 oz = $0.30 per oz.
Step 2: Calculate Brand B unit rate: $4.80 ÷ 16 oz = $0.30 per oz.
Step 3: Compare: Both brands cost exactly $0.30 per ounce.
Step 4: Either brand offers the same value per ounce.
