Question: John buys 3 dress shirts. They sell for $20 each. He also has to pay 10% tax on everything. How much did he pay in total? Think carefully first, then make a decision:
The shirts cost 3 * $20 = $60 before tax. The tax cost $60 * .1 = $6. So in total they paid $60 + $6 = $66. So the answer is 66.
