You buy 3 bags of takis for $2.25 each. The sales tax is 8%. what was your total after tax

AnnyKZ [126]

Answer: <u><em>$7.29</em></u>

Step-by-step explanation: First you need to multiply 3 by 2.25 because you are buying 3 bags of takis. → 3*2.25= $6.75

Then you need to turn 8%a decimal. 8 percent is 8 out of 100% thus

8/100 or .08.

You need to multiply .08 by 6.75 and then you get your answer of $7.29 for three bags of takis with a 8% tax.

Hope I helped!
