Final answer:
The 5 pounds from the local roaster would cost $0.45 more than 5 pounds of the store brand.
Step-by-step explanation:
To find out how much more 5 pounds from the local roaster would cost than 5 pounds of the store brand, we need to calculate the cost of each option. The store brand costs $1.23 per pound, so 5 pounds of the store brand would cost 5 * $1.23 = $6.15. The local roaster charges $1.98 per 1 1/2 pounds, which is equivalent to $1.98 * 2/3 = $1.32 per pound. Therefore, 5 pounds from the local roaster would cost 5 * $1.32 = $6.60.
To find the difference in cost, we subtract the cost of the store brand from the cost of the local roaster: $6.60 - $6.15 = $0.45. Therefore, 5 pounds from the local roaster would cost $0.45 more than 5 pounds of the store brand.
