Answer:
4% sales tax
Step-by-step explanation:
Take the original costs and subtract it from the price after sales tax.
$84.24-$81= $3.24
Divide 3.24 by 81
this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
i looked it up and it is false
36 most likely
4, 8, 16, 32, 64 is a pattern. You multiply by 2 to get the next term. I would think 36 doesn't belong for this reason.
Answer: the correct answer would be no solution.
