Answer:

1.  2.4

2. 4.444

Step-by-step explanation:

First, let's look at 4/5 of 3. We can set it up like this:

<h2>3 * \frac{4}{5}</h2>

Next, multiply the 3 by the 4 to get this:

<h2>\frac{12}{5}</h2>

Then, if a calculator is permitted, we get the answer of 2.4.

The next thing to do would be to repeat the steps for 2/9 of 20.

20 * \frac{2}{9}

\frac{40}{9} = 4.444

<em><u>Problem One</u></em>

Remark

You don't pay a sales tax until cash is exchanged for goods or services.

So what is 70% off

Solution

Sale price = given price * (100% - 70%)

Sale Price = 72 * 30%

Sale Price = 72 * 30/100

Sale Price = 72 * 0.3

Sale Price = 21.6 dollars.

The sales tax is 5% of this amount

21.6 * 5/100 = 1.08

The total cost is = 21.6 + 1.08 = 22.68

Problem Two

If they marked up 100%, effectively they doubled the price.

New Price = old price + 100% of old price.

New Price = 48.50 + 48.50 = 97 dollars.

The sales tax is 6% * 97 = 6/100 * 97 = 5.82

Total Cost = Cost of item + Tax

Total Cost =97 + 5.82

Total Cost = 102.82 Answer <<<<
