A 4-pint carton of soy milk costs $5.60. What is the price per cup?
$
To find the price per cup, we need to first determine the number of cups in 4 pints.
Since 1 pint is equal to 2 cups, 4 pints would be equal to 4 * 2 = <<4*2=8>>8 cups.
The cost of 4 pints of soy milk is $5.60, so the price per cup would be $5.60 / 8 cups = $0.70.
Therefore, the price per cup is $0.70.
