A candy store sells different types of candy by the ounce red snaps cost .25 per ounce and blue tarts cost .30 per ounce you decide to buy 8 ounces of candy to share with your friends how much more expensive would it be to get a bag of blue tarts instead of a bag of red snaps? .40 $2.00 $4.40 $2.40
To find out how much it would be to get a bag of red snaps, you multiply the cost per ounce by the number of ounces bought: .25 * 8 = $<<.25*8=2.00>>2.00
To find out how much it would be to get a bag of blue tarts, you multiply the cost per ounce by the number of ounces bought: .30 * 8 = $<<.30*8=2.40>>2.40
To find out how much more expensive the blue tarts are than the red snaps, you subtract the cost of the red snaps from the cost of the blue tarts: 2.40 - 2.00 = $<<2.40-2.00=0.40>>0.40. Answer: \boxed{0.40}.
