Answer:

65.60

Step-by-step explanation:

First find the markdown

markdown = original price times the percent markdown

                  = 80* 18%

                  = 80 * .18

                     14.4

Take the markdown from the original price to find the retail price

80-14.4 =65.60

Determine whether 52c2y4 is a monomial, binomial, trinomial, or other polynomial.
neonofarm [45]

Answer: Monomial.

Step-by-step explanation:

Ok, when we have a polynomial with only one term, this is a monomial.

If the polynomial has two terms, this is a binomial.

If the polynomial has 3 terms, this is a trinomial.

And so on.

In this particular case we have:

52*c^2*y^4

Where c and y may be variables.

We can see that here we have only one term, so this would be a monomial.

(notice that the number of variables does not affect the type of polynomial in this case, only the number of terms)

4. A store had 86 DVDs and 52 CDs. When the equal number of DVDs and CDs were sold,
11Alexandr11 [23.1K]

Answer:

51 DVDs

Step-by-step explanation:

Let the number of DVDs and CDs sold be x each.

<u>Initial</u>

Number of DVDs= 86

Number of CDs= 52

<u>After selling</u>

Number of DVDs= 86 -x

Number of CDs= 52 -x

Given that there are 3 times as many DVDs than CDs left,

86 -x= 3(52 -x)

<em>Expand:</em>

86 -x= 156 -3x

<em>Bring x terms to 1 side, constant to the other:</em>

3x -x= 156 -86

<em>Simplify:</em>

2x= 70

<em>Divide both sides by 2:</em>

x= 35

Amount of DVDs left

= 86 -x

= 86 -35

= 51
