1 answer

To compare the two options, we need to calculate the unit price (price per pound) for each choice.

Option 1: $12.95 for 3 pounds of nuts
To find the unit price:
\[ \text{Unit rate for option 1} = \frac{12.95}{3} \approx 4.32 \]

Option 2: $21.45 for 5 pounds of nuts
To find the unit price:
\[ \text{Unit rate for option 2} = \frac{21.45}{5} = 4.29 \]

Now we can compare the unit rates:

  • Option 1: approximately $4.32 per pound
  • Option 2: $4.29 per pound

Conclusion: The better buy is the second option, which offers the nuts at approximately $4.29 per pound, compared to $4.32 per pound in the first option.
