To determine how much more expensive it would be to get a bag of blue tarts instead of a bag of red snaps, we need to compare the costs of the two options.
The cost of red snaps is $0.25 per ounce. So, for 8 ounces of red snaps, the total cost would be:
Total cost of red snaps = Cost per ounce × Number of ounces = $0.25 × 8 = $2.00
The cost of blue tarts is $0.30 per ounce. So, for 8 ounces of blue tarts, the total cost would be:
Total cost of blue tarts = Cost per ounce × Number of ounces = $0.30 × 8 = $2.40
To find the difference in cost between the two options, we subtract the cost of red snaps from the cost of blue tarts:
Difference in cost = Total cost of blue tarts - Total cost of red snaps = $2.40 - $2.00 = $0.40
Therefore, the correct answer is B. $0.40. It would be $0.40 more expensive to get a bag of blue tarts instead of a bag of red snaps.
