Jake has 49 fewer peaches and 32 more apples than Steven. Steven has 47 peaches and 17 apples. How many apples does Jake have?
Jake has 49 fewer peaches than Steven. 
That means Jake has 47 - 49 = -2 peaches. 
That can't be right, so Jake must have 47 + 49 = 96 peaches. 

Jake has 32 more apples than Steven. 
That means Jake has 47 + 32 = 79 apples.
