###Human: Sandra has a box of apples that weighs 120 pounds.  She's going to use half the weight in apples to make applesauce.  The rest will be used to make apple pies.  She needs 4 pounds of apples per pie.  How many pies will she be able to make?, ### Assistant: The box weighs 120 pounds and she's going to use half of it to make applesauce so she'll use 120/2 = 60 pounds for applesauce
The box weighs 120 pounds and she'll use 60 pounds for applesauce so that leaves 120-60 = 60 pounds of apples
She has 60 pounds of apples and she needs 4 pounds to make a pie so she can make 60/4 = 15 pies 
 So the answer is :  15
