Problem: Arturo paid \$8 in tax on a purchase of \$200. At that rate, what would the tax be on a purchase or \$150?

Changed to : Arturo paid \$8 in tax on a purchase. WDYN? WDYW?

I thought then students should make estimates on how much the item he purchased cost to have \$8 in taxes. Having students partner share and then share with the class.

Eventually I will reveal he spent \$200.

Then I can have students find out how much tax he would spend on other purchases if the rate was the same. Or I can give them another tax amount and have them estimate how much was spent before moving onto how much tax it would be for a specific purchase.Problem: Arturo paid \$8 in tax on a purchase of \$200.
