Question

2.5 kg of potatoes cost ￡1.30 Work out the cost of 4.25 kg of potatoes. Optional working

Answer 1

Firstly, Find the unit cost of the potatoes: ### \( £ 1.30 / 2.5 kg = £ 0.52 per kilo \) Next, calculate the cost for 4.25 kilos of potatoes: ### \( £ 0.52 per kilo \times 4.25 kg = £ 2.21 \) So, 4.25 kg of potatoes costs £2.21

Answer 2

## Step 1: Firstly, Determine the cost of potato per kilogram. To find this, we divide the total cost of 2.5kg potatoes by the weight in kilogram (2.5kg). Carrying out the above operation in LaTeX: ### \( \textbf{Cost per kilogram} = \frac{\textbf{Total Cost}}{\textbf{Weight}} = \frac{£1.30}{2.5kg} \) ## Step 2: In this step, we need to calcuate the answer from operation in Step 1. Let's apply the values to the formula. After finding the unit cost per kilogram, the next step is to calculate the cost for 4.25kg of potatoes by using the following formula in LaTeX: ### \( \textbf{Cost for 4.25 Kg} = \textbf{Cost per kilogram} \times \textbf{Weight} = \textbf{Cost per kilogram} \times 4.25kg \)
