To calculate the price difference, we need to subtract the cost of Red Snaps from the cost of Blue Tarts per ounce, and then multiply that difference by the total number of ounces, which is 8.
The cost of Red Snaps per ounce is $0.25.
The cost of Blue Tarts per ounce is $0.30.
The difference in cost per ounce is $0.30 - $0.25 = $0.05.
Therefore, the cost difference for 8 ounces is $0.05 * 8 = $<<0.05*8=0.40>>0.40.
So, it would be $0.40 more expensive to get a bag of Blue Tarts instead of a bag of Red Snaps.
