Sheldon needs to buy 8 gallons of ice cream, $2.50 for 1 pint and $4.50 for 1 quart. which is the better deal

To get the answer to that, first let's convert the pint and quart into gallons so that it will be easier to answer. So for the pint, 1 pint is equal to 0.125 gallons. For the quart however, 1 quart is equal to 0.25 gallons. Next, we multiply 8 with 2.5 and 4.5 to get the total cost for each. 8 x 2.5 is 20 and 8 x 4.5 is 36. Obviously we know that know that the quart costs more than the pint but the quart has double what the pint has and the difference of the price is only 16 dollars. So I'd say the better deal is the quart
