During the harvest, 13485 apples were picked. Week one, 4,589 apples were sold. Week two, 2,113 apples were sold. How many apples are left after two weeks?
6,783 apples are left.
Explanation:
During the harvest, 13485 apples were picked.
Week one, 4,589 apples were sold.
Week two, 2,113 apples were sold.
Total apples sold in two weeks 4,589 + 2,113 = 6,702
Number of apples left after two weeks
13,485 – 6,702 = 6,783

Example 1
STEP 1 Find how many apples were left after week 1.

8,896 apples.

Explanation:
During the harvest, 13485 apples were picked.
Week one, 4,589 apples were sold.
Number of apples left
13,485 – 4,589 = 8,896

STEP 2 Find how many apples were left after week 2.

So, the Yummy Apple Orchard had ___________ apples left after two weeks.

Explanation:
Apples sold during week two = 2,113
Apples left after week one = 8,896
Apples left after week two = 8,896 – 2,113 = 6,783

How does Step I differ from Step 2?
In step two we find the apples left in week one.
In step two we find apples left in week two.
