Claire for to a show sale. Everything on the shelf is 35% off the marked price. She falls in love with a pair of red heels that

lyudmila [28]

Percentage of discount on the Marked price = 35%
Marked price of the pair of red heels that Claire falls in love with = $64.99
Then
Amount of discount on the
marked price of the pair of red heels = (35/100) * 64.99 dollars
   = 0.35 * 64.99 dollars
   = 22.746 dollars
   = 22.75 dollars
Then
Price of the red heels after discount = (64.99 - 22.75) dollars
   = 42.24 dollars
Percentage of sales tax that needs to be given by Claire = 7.5%
Amount of sales tax that needs to be given by Claire = (7.5/100) * 42.24 dollars
   = 316.80/100 dollars
   = 3.168 dollars
   = 3.17 dollars
Then
The total price of the
red heels that Claire has to pay = (42.24 + 3.17) dollars
   = 45.41 dollars
So Claire has to pay a total of $45.41 for the pair of red heels she has fallen in love with.

There are 53 students on the Jackson Middle School basketball teams. The number of 8th graders is 15 fewer than three times the

pshichka [43]

Answer:

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Step-by-step explanation:

Let

x ----> the number of 7th students on the Jackson Middle School basketball teams

y ----> the number of 8th students on the Jackson Middle School basketball teams

we know that

There are 53 students on the Jackson Middle School basketball teams

so

$x+y=53$ -----> equation A

The number of 8th graders is 15 fewer than three times the number of 7th graders

so

$y=3x-15$ ----> equation B

substitute equation B in equation A

$x+(3x-15)=53$

solve for x

$x+3x=53+15\\4x=68\\x=17$

Find the value of y

$y=3(17)-15=36$

therefore

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Setler79 [48]

Answer and Step-by-step explanation:

According to the given situation, The r-value associated with the ordered pairs for the linear function is very nearest to zero which does not results in adequate presentation of the outcome.

A quadratic model could properly comprise of a combination of data, as the set of data has a turning point.

This result in data rises and falls which represents the graph of quadratic's graph
