Hey,

Solution,

Marked price(MP)= $ 80

Discount percent= 20%

Now,

Discount amount=discount percent of MP

 = 20% of 80

 =20/100*80

 = $ 16

Again,

Selling price(SP)=MP - Discount amount

 =$80 -$16

So,the sale price of the CD player is $ 64.

Hope it helps...

Good luck on your assignment....

Stay safe...

If the CD player sells regularly for $80 but is on sale for 20% off the sales price will now be $64. The equation used is ? x 0.8 = 20%. Think of teams of 10. 8+2 = 10 right? Now put transfer that to hundreds 80+20 = 100 or in this case 1 whole number. To get a certain percent off you need to x it by 0. (Other part of teams of 10) so if it was 63% off you would do ? x 0.37. If you want to keep it simple though just times the original number, in this case 80, by 0. And then the percentage ( 80 x 0.60 ) that’ll give you how much to take off of $80 to reach 20% off.

Answer:

$f(g(x))=\frac{1}{(x^{2}+1)^{2}} +\sqrt[3]{x^{2}+1}$

Step-by-step explanation:

we have

$f(x)=x^{2} +\frac{1}{\sqrt[3]{x}}$

$g(x)=\frac{1}{x^{2}+1}$

we know that

In the function

$f(g(x))$

The variable of the function f is now the function g(x)

substitute

$f(g(x))=(\frac{1}{x^{2}+1})^{2} +\frac{1}{\sqrt[3]{(\frac{1}{x^{2}+1})}}$

$f(g(x))=\frac{1}{(x^{2}+1)^{2}} +\sqrt[3]{x^{2}+1}$

Kim purchased 6 small containers of potato salad and Seth purchased 2 extra large containers of potato salad. What is the differ

icang [17]

I am assuming that the attached is the complete question and we need to get the information from the table.

From the table we know the below fact:

$1 \; small \; container \; of \; potato \; salad \; Weighs \; \frac{2}{8} \; pounds\\\\1 \; extra \; large \; container \; of \; potato \; salad \; Weighs \; \frac{9}{8} \; pounds$

$Weight \; of \; 6 \; small \; container = 6 \times \frac{2}{8} = \frac{12}{8} \; pounds\\\\Weight \; of \; 2 \; Extra \; large \; container = 2 \times \frac{9}{8} \; = \; \frac{18}{8} \; pounds$

Conclusion:

The difference in weights, in pounds of Kim’s and Seth’s purchases is given below:

$\frac{18}{8} - \frac{12}{8} = \frac{18-12}{8} = \frac{6}{8} \\\\Simplifying \; the \; fraction \; dividing \; by \; 2 \; on \; both \; numerator \; and \; denominator\\\\ \frac{6 \div 2}{8 \div 2} = \frac{3}{4}$
