To solve this problem, we can turn it into an equation with just one variable. To do this, we can put everything in terms of how many apples James picked. Because James picked an unknown amount of apples, we can make this the variable j. Because Kari picked 10 pounds more, we can make Kari's apples j + 10. Because Sandy picked 10 pounds more of apple than Kari, and Kari picked 10 pounds more of apple than James, we can turn this into j + 10 + 10, or j + 20.

 

 

Therefore, our equation can be:

 

j + j + 10 + j + 20 = 156

(Combine terms into the same place)

j + j + j + 10 + 20 = 156

(Combine like terms)

3*j + 30 = 156

(Subtract 30)

3 * j = 126

(Divide by 3)

j = 42

 

 

Now we know that James picked 42 apples. From this, because we know that Sandy picked 20 more apples than James, we can just add 20 to 42 and have our answer. So:

 

20 + 42 = 62

 

 

Sandy picked 62 apples.

We want how many apples  's' picked ...so if possible put everything in terms of 's'

 

s = k+10        k = s-10

k = j+10         s-10 = j+10    so  j = s-20   

 

s    + s-10    + s-20 = 156

s = 62 pounds
