Answer 2

Step-by-step explanation:

Given A grocer stacks apples in a pyramid-like stack whose rectangular base is 7 apples by 8 apples. Each apple above the first level rests in a pocket formed by four apples below. The stack is completed by a single row of apples. How many apples are in the stack?

• So the apples are placed in a pyramid like shape. It has a rectangular base. In this the apples are 7 by 8. So the first level is on a pocket formed by 4 apples below. Now from last to first that is from bottom to top each row will be one less apple in both sides.
• So we get this as
• 6 x 7
• 5 x 6
• 4 x 5
• 3 x 4
• 2 x 3
• 1 x 2
• Now we have in the single row of apples, the stack is finished.
• 7 x 8 + 6 x 7 + 5 x 6 + 4 x 5 + 3 x 4 + 2 x 3 + 1 x 2
•  56 + 42 + 30 + 20 + 12 + 6 + 2
•                = 168
• So there are 168 apples in the stack
