Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
Gnoma [55]

Answer:

<em>Tiffany pays a total price of $9.81 for the basket of watermelons</em>

Step-by-step explanation:

<u>Percentages</u>

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

yawa3891 [41]

Explanation:

Each box contains

\begin{gathered} 6plain \\ 4blueberry \\ 2onionbagels \end{gathered}

The ratio that compares the number of blueberry bagels in one box to the number of onion bagels in one box will be calculated below as

\begin{gathered} 4:2 \\ in\text{ the simplest form } \\ 2:1 \end{gathered}

This means that for every one onionbagels in the box, there are 2 blueberry bagels

Part B:

Given that there are 20 blueberry bagels, the number if onion bagels will be calculated below as

\begin{gathered} \frac{2}{1}=\frac{20}{x} \\ cross\text{ multiply, we will have} \\ 2x=20 \\ \frac{2x}{2}=\frac{20}{2} \\ x=10 \end{gathered}

Hence,

The final answer is

10\text{ }onion\text{ }bagels
