To find out how much more expensive it would be to get a bag of blue Tarts compared to red snaps, we need to calculate the total cost for each type of candy for 8 ounces.
Cost of red snaps:
- Cost per ounce: $0.25
- Total cost for 8 ounces: \( 8 , \text{oz} \times 0.25 , \text{dollars/oz} = 2.00 , \text{dollars} \)
Cost of blue Tarts:
- Cost per ounce: $0.30
- Total cost for 8 ounces: \( 8 , \text{oz} \times 0.30 , \text{dollars/oz} = 2.40 , \text{dollars} \)
Difference in cost:
- Difference: \( 2.40 - 2.00 = 0.40 , \text{dollars} \)
So, it would be $0.40 more expensive to get a bag of blue Tarts instead of a bag of red snaps.
The correct answer is C. 0.40.
