Math Worksheet - Calculating Tax

Now that we've got some basics of math covered off - rounding and order of operations - we can start to build on those with some real life scenarios.

Calculating the tax is something we all should know how to do. Often it is done for us (buying groceries, eating out, etc), but it is always good to know how to calculate it to help us plan ahead. We recently to a friend of Holly's skiing for the day. We have season's passes, but her friend had to buy a ski pass for the day. We googled how much the day pass would be, but taxes were not included in the cost. Should we bring only the $30 for the day pass? Should we bring $35? Would that be enough? Doing some quick math, using a 15% tax rate as an estimate, we estimated ($30 times 10%) + ($30 times 5%) is $3 + $1.50 = $4.50. So, $35 was just enough.

Here are some worksheets, with answers, on calculating taxes.
