HELP PLS use the original price and markup to find the retail price. original price $68 markup 20%
insens350 [35]

Answer: $81.60

Step-by-step explanation:

When we have an original price OP, and a markup of X% (this is how much increases the price with respect to the original price)

The retail price will be:

RP = OP + (X%/100%)*OP

RP = OP*(1 + X%/100%)

In this case, we have:

Original price = OP = $68

markup = X% = 20%

Replacing these in the above equation, we get:

RP= $68*(1 + 20%/100%) = $68*(1 + 0.20)

RP = $68*(1.20) = $81.60

Then the retail price of this particular item is $81.60

Find the zeros of the function f(x)=2x^2-7x-30
ivanzaharov [21]
2x^2-7x-30=0 \\ \\
a=2 \\ b=-7 \\ c=-30 \\
b^2-4ac=(-7)^2-4 \times 2 \times (-30)=49+240=289 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-(-7) \pm \sqrt{289}}{2 \times 2}=\frac{7 \pm 17}{4} \\
x=\frac{7-17}{4} \ \lor \ x=\frac{7+17}{4} \\
x=\frac{-10}{4} \ \lor \ x=\frac{24}{4} \\
x=-\frac{5}{2} \ \lor \ x=6 \\
\boxed{x=-2.5 \hbox{ or } x=6}

From eight different books, in how many ways can any four of them be arranged side by side on a bookshelf?
Snezhnost [94]
First we calculate how many ways you can choose four books from a set of eight.
We use the formula n! / [r! * (n-r)!]

8! / [4! * 4!]

= 8*7*6*5 / 4*3*2*1 = 70 ways

Then we have to calculate how many permutations can be made from 4 objects which equals 4*3*2*1 = 24

So, the TOTAL number of ways = 70 * 24 = 1,680
