Good work! 
Find the following skills on IXL. The more you practice, the more ready you'll be for our assessment tomorrow.

They may have MORE steps than our usual percent problems:
Search "PBM" Find the percent, tax, discount, and more
Search "BDA" Sales prices: find the original price

Prep--Make a plan for how you will get ready for our End of Module Assessment tomorrow. Answer at least one of the following prompts:

Is there a problem (questions 1 through 8) from today's classwork that you need to review how to solve? Explain.

Will you review lessons in your notebook? If so, which lessons?

Will you get extra practice from IXL? If so, which skills?
