Question: Martha needs 4 cups of berries and 2 cups of heavy cream to make 1 quart of ice cream.  She wants to make 1 quart of strawberry ice cream and 1 quart of raspberry ice cream.  At the farmers market, the 2 cup packages of strawberries are $3.00 each and the 2 cup package of raspberries are $5.00 each.  The heavy cream is sold for $4.00 for a 4 cup container.  How much will it cost her to make 1 quart of each ice cream?
Solution:
She needs 4 cups of strawberries per quart of ice cream and the strawberries are sold in 2 cup packages. So 4/2 = 2 packages of strawberries
The strawberries cost $3.00 per package and she needs 2 so 3*2=$6.00
She needs 4 cups of raspberries per quart of ice cream and the raspberries are sold in 2 cup packages. So 4/2 = 2 packages of raspberries
The raspberries cost $5.00 per package and she needs 2 so 5*2 = $10.00
Every quart needs 2 cups of heavy cream and she's making 2 quarts so 2*2 = 4 quarts
She will spend $6.00 on strawberries, $10.00 on raspberries and $4.00 on heavy cream bringing the total to 6+10+4 = $20.00
