Identify food items with a decrease in both month-on-month and year-on-year percentage change.

Step 1: Identify food items with a decrease in both month-on-month and year-on-year percentage change. We look for negative values in both "YEAR ON YEAR" and "MONTH ON MONTH" columns. • For 750 ml sunflower oil: Year-on-year change is -12.7\% and month-on-month change is -2.3\%. Both are decreases. • For Oranges per kg: Year-on-year change is -8.9\% and month-on-month change is -14.5\%. Both are decreases. The food items are 750 ml sunflower oil and Oranges per kg. Step 2: Determine the missing value, A. Value A is the total price in May 2022. We sum all the prices in the "MAY 2022" column. A = 12.60 + 45.56 + 52.97 + 40.68 + 22.07 + 37.73 + 86.80 A = R298.41 The missing value is R298.41. Step 3: Calculate the price of a dozen eggs during May 2022. From the table, the price of "Eggs 1,5 dozen tray" in May 2022 is R52.97. Since 1.5 dozen = 1.5 × 12 = 18 eggs, the price for 18 eggs is R52.97. To find the price of 1 dozen (12 eggs), we divide the price of 1.5 dozen by 1.5. Price per dozen = R52.971.5 Price per dozen = R35.3133... Rounding to two decimal places for currency: Price per dozen = R35.31 The price of a dozen eggs during May 2022 is R35.31. Step 4: Write down the unit ratio for the price of oranges in May 2022 to the price of oranges in May 2023. Price of oranges in May 2022 = R22.07 Price of oranges in May 2023 = R20.10 The ratio is May 2022 price : May 2023 price. Ratio = 22.07 : 20.10 To express this in the form 1 : , we divide both sides by the first term (22.07). 1 : (20.10)/(22.07) 1 : 0.91073855... Rounding to three decimal places: 1 : 0.911 The unit ratio is 1 : 0.911. Send me the next one 📸
