To determine which is a better deal, we'll calculate the cost per pound for each option.
For 8 pounds of rice at $10.40:
Cost per pound = Total cost / Total pounds
Cost per pound = $10.40 / 8 pounds = $1.30 per pound
For 10 pounds of rice at $12.00:
Cost per pound = Total cost / Total pounds
Cost per pound = $12.00 / 10 pounds = $1.20 per pound
Comparing the two costs per pound, you can see that 10 pounds of rice for $12.00 is the better deal, as it costs $1.20 per pound compared to $1.30 per pound for 8 pounds of rice. So, buying the 10-pound option is more cost-effective.
