Question

At a supermarket, potatoes cost £1.12 per kilogram and mince costs £5.60 for 0.5 kilograms. a) Calculate the cost of the potatoes needed for the recipe. b) Calculate the cost of the mince needed for the recipe. c) Work out the total cost of the mince and potatoes for the recipe.

Answer 1

To calculate the cost of ingredients for a recipe, multiply the cost per unit by the quantity required. For example, if 2kg of potatoes at £1.12/kg and 1kg of mince at £11.20/kg are needed, calculate as (£1.12 * 2) for potatoes and (£11.20 * 1) for mince. Add these to get the total cost.

Step-by-step explanation:

Given the price of potatoes and mince, to find the cost of the potatoes and mince for the recipe, you'll first need to know the quantity needed for the recipe. For instance, if the recipe requires 2 kilograms of potatoes and 1 kilogram of mince, the calculations would be as follows:

a) Potatoes: £1.12 per kilogram * 2 kilograms = £2.24.

b) Mince: £5.60 is the cost for 0.5 kilograms, so for 1 kilogram (which is twice the amount), the cost will be £5.60 * 2 = £11.20.

c) Total cost: Add the cost of the potatoes (£2.24) and the cost of the mince (£11.20) to get the total cost: £2.24 + £11.20 = £13.44.

These calculations will vary depending on the quantities required in your recipe. The formula to remember here is Cost per Unit * Quantity.
