The formula used to calculate the percentage is (value/total value)*100%.

Step-by-step explanation:

Step 1 of 2

The original price of coat = $180



Ajax always sells at 50% discount

So their sale price = $90

Step 2 of 2

On Saturdays they sell 20% less

Which implies-

1/5*90 = 18

90-18=72

They sell at $72 on Saturday.

Thus, conducting the survey so that the sample is biased toward overturning the ban is to increase the number of people not favoring the skateboarding ban in comparison to people who are favoring the ban.

Step-by-step explanation:

Given:

A survey regarding the decision on banning skateboarding

To find:

how the poll may be conducted in such a way that the sample is skewed in favor of reversing the prohibition

Explanation:

A reasonable sample is
● selected at random,
● representative of the population, and
● large enough to provide accurate data.

While taking the sample, the number of people who are not favoring the ban on skateboarding should be increased in comparison to the number of people who are in favor of the ban. Doing so will result in a biased sample indicating that majoring of people do not want to ban skateboarding as the sample is projecting a majority who are against the ban instead of favor the ban.

Step-by-step explanation:

the discount is $16.35

Answer:

15% = $16.35

Step-by-step explanation:

To find the amount, lets find 10% first. To do so, move the decimal one place to the left.

10%= $10.90

Now, lets find half of 10% value to add it up to deal, 15% off.

10.90/2= 5.45

5%= 5.45

Now, we must add the values of 10% and 5% to find the discount off of the stereo.

10.90 + 5.45 = 16.35

15% = $16.35

Your discounted amount will be $16.35.

Answer:

x=12

Step-by-step explanation:

[tex]16+20+2x=60\\36+2x=60\\2x=24\\x=12[/tex]

the perimeter is the side lengths added together meaning it is

[tex]16+20+x+x=60[/tex]. x+x can be simplified to 2x. now solve for x

Answer:

x = 12 ft

Step-by-step explanation:

We know that by adding up all of the values of the sides, we will get the value of the perimeter. Using this information, we can set up an equation and simplify to find the variable.

16 + 20 + x + x = 60                         <----- The sum of the sides is the perimeter

16 + 20 + 2x = 60                            <------ Combine variables (x + x = 2x)

36 + 2x = 60                                    <----- Add 16 and 20

2x = 24                                            <----- Subtract 36 from both sides

x = 12                                               <----- Divide both sides by 2

Answer:

B

Step-by-step explanation:

Answer:

Karl could have saved $2.50

Step-by-step explanation:

Cost of folders without the sale: 2.5*5 = $12.50

Cost of folders with the sale: 0.8*2.5 = $2 per folder * 5 folders = $10.00

Difference between prices: 12.5-10 = $2.50

Answer:

2.50$ Karl could have saved on the purchase by waiting a day.

Step-by-step explanation:

Given: total number of folders Karl bought is 5 .

The cost of each folder is 2.50$.

20% off sale the following day at Pay-A-Lot.

we have to find the 20% of each folder and then add them to get the final saving of Karl if he had waited for a day.

Step 1 of 2

20% of 2.50$ is equal to

[tex]$$\begin{aligned}&=2.50 \cdot 20 \% \\&=2.50 \cdot \frac{20}{100} \\&=0.50 \$\end{aligned}$$[/tex]

this is the amount Karl would save on each folder if waited for a day or this is the discount on the amount of 2.50$ that the shopkeeper will give the next day on each

Step 2 of 2

Karl bought 5 folders

so, total savings would be equal to

[tex]$$\begin{aligned}&=5 \cdot 0.50 \\&=2.50 \$\end{aligned}$$[/tex]
