1. A student estimated that it would take 3 hours to write a book report, but it actually took her 5 hours. What is the percent error for her estimate?

6A. For diagram A, decide if y is an increase or decrease of x. Then, determine the percentage.

Increase: y is a 25% increase of x.

Decrease: y is a 20% decrease of x.

Decrease: y is a 25% decrease of x.

Increase: y is a 20% increase of x.

6B. For diagram B, decide if y is an increase or decrease of x. Then, determine the percentage.

Increase: y is a 50% increase of x.

Decrease: y is a 50% decrease of x.

Increase: y is a 60% increase of x.

Decrease: y is a 60% decrease of x.
