Question

Ivan paid 14.98 for a 7.26kg bag of dog food. A few weeks later, he paid 17.54 for a 7.94 kg bag at a different store.
Find the unit price for each bag. Then state which bag is the better buy based on the unit price.

Round your answers to the nearest cent.

Answer 1

To find the unit price for each bag of dog food, we need to divide the total price by the weight in kilograms.

### For the first bag:
- Price: $14.98
- Weight: 7.26 kg

Unit price = Total price / Weight
\[
\text{Unit price for first bag} = \frac{14.98}{7.26} \approx 2.06
\]
Rounded to the nearest cent, the unit price is **$2.06 per kg**.

### For the second bag:
- Price: $17.54
- Weight: 7.94 kg

Unit price = Total price / Weight
\[
\text{Unit price for second bag} = \frac{17.54}{7.94} \approx 2.21
\]
Rounded to the nearest cent, the unit price is **$2.21 per kg**.

### Comparing the unit prices:
- First bag: **$2.06 per kg**
- Second bag: **$2.21 per kg**

The first bag is the better buy because it has a lower unit price of **$2.06 per kg** compared to **$2.21 per kg** for the second bag.
