What is 16.2 simplified (and 121 simplified to)
Cerrena [4.2K]

Answer:

16.2 = \frac{81}{5} and 121 = \frac{121}{1}

Step-by-step explanation:

  • 16+\frac{2}{10} =\frac{81}{5} which is 16.2

121 is already simplified since it is a whole number, but its fraction form would be \frac{121}{1}

  • 121+\frac{0}{10} =121 which is 121

You are on vacation and want to buy a pair of sunglasses for $15 or less. You find a pair with a price tag of $11. The cashier s
denis23 [38]

Answer:

No, this is not the correct amount.

Step-by-step explanation:

Assuming this purchase is being made in the USA, the average federal tax rate on purchased goods is between 2.9% and 7.25% of the price. Let's be generous and assume that wherever you're making this purchase, the sales tax is 7.25%.

7.25% of 11 = .7975, or .80 cents. Add that to 11 to get $11.80.

The extra 91 cents tax is around 12.09% tax which is a lot higher than normal. You're being ripped off!
