Answer 1

Answer:200

Explanation:

Answer 2

• No, different

Explanation:

Last year

Bought 40 sets

Sold 25 sets

• Error = 25 - 40 = -15
• Absolute error = | - 15| = 15
• Percent error = 15/40*100% = 37.5%

This year

Bought 75 sets

Sold 60 sets

• Error = 60 - 75 = -15
• Absolute error = |-15| = 15
• Percent error = 15/75*100% = 20%

We can see absolute errors are same but percent errors are different.

The reason is the referenced numbers are different.
