A farmer sells a total of 662,821 pounds of apples. Below is the number of pounds each type of apple the farmer sold.

Granny Smith: 322,867

Red Delicious: 123,457

McIntosh: M

Part A: Which is the closest estimate of the number of pounds of McIntosh apples the farmer sold?

Part B: Find the actual number of pounds of McIntosh apples the farmers sold.

Part C: Is your answer reasonable? Explain

Part A: 

• Granny Smith:  322,867≈323,000
• Red Delicious: 123,457≈123,000

Sum of estimated Granny Smith and Red Delicious:

323,000+123,000=446,000

Estimated McIntosh pounds:

662,821−446,000=216,821

The closest estimate of McIntosh apples sold is approximately 217,000 pounds.

Part B:

M=662,821−(322,867+123,457)

First, sum Granny Smith and Red Delicious:

322,867+123,457=446,324

Now subtract:

M=662,821−446,324=216,497

So, the actual pounds of McIntosh apples sold is 216,497 pounds.

Part C:

Yes, the answer is reasonable because:

• The sum of Granny Smith and Red Delicious apples plus McIntosh apples equals the total number of apples sold.
• The estimate in Part A (217,000 pounds) is close to the actual value (216,497 pounds), showing the estimation was accurate.
• The number is positive and makes sense given the total and the other quantities.
