A local discount store is famous for their motto, "Shop with us and you'll pay 20% less". Their claim is that every item in the

store is already marked down 20% off of retail prices. In this Sunday's ad, they are advertising a scuba mask and snorkel set at their discount price of $28. Use a percent model to determine the original retail price of the scuba mask and snorkel set.

Answer:

Original retail price: $35

Step-by-step explanation:

20% off means that the discounted price is equivalent to 80% (100% - 20%) of the retail price.  

Calling x the retail price of the scuba mask and snorkel set, then a discounted price of $28 means that this amount of money is 80% of x. Mathematically:

80*x/100 = $28

x = $28*100/80

x = $35

Use percentage multipliers:
$28/0.8 = $35
The original price of the set is $35.

Hope This Helps!

The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of
Rainbow [258]

Answer:

No units

Step-by-step explanation:

The cost function is given by;

C(x)=x^2-20x+35

To find the units manufactured at a cost of $5,560

We equate the C(x) to 5560 and solve for x.

x^2-20x+35 = 5560

x^2-20x+35 - 5560 = 0

x^2-20x - 5525= 0

The discriminant of this equation is negative.

That is,

d =  {( - 20)}^{2}  - 4 \times 1 \times  - 5560 \:  < 0

Hence the equation has no real roots.

This means no units can be produced at $5,560

Which box plot correctly displays the data set with a maximum of 48, a minimum of 27, a median of 36, an upper quartile of 45, a
Vitek1552 [10]

Answer:

Image 1

Step-by-step explanation:

To answer this question, we need to know how to use a box plot.

I've attached an image that demonstrates this well and can teach you what each part of the box plot means.

Specifically, the 2 farthest dots at the end are the minimum and maximum. The two sides where the box starts are the lower and upper quartiles. Finally, the line in the middle of the box is the median.

With this, we can analyze each box plot and determine which one is correct.

<em><u>Box Plot 1: </u></em><em>Everything is plotted correctly- Maximum and minimum plotted correctly, median plotted correctly, upper and lower quartile plotted correctly.</em>

<u>Box Plot 2:</u> Everything plotted correctly EXCEPT maximum of 48 is represented at 46.

<u>Box Plot 3:</u> Everything plotted correctly EXCEPT the upper quartile of 45 is at 39.

<u>Box Plot 4:</u> Upper quartile represented at 39 and maximum represented at 46 are both incorrect.
