A bookstore buys Algebra 1 books at a wholesale price of $23 each. It marks up the price by 92% and then sells the Algebra 1 boo
IceJOKER [234]

Answer:

The mark up is $21.16 and the final selling price is $44.14

Step-by-step explanation:

To find the mark up price, you simply multiply the cost by the mark up percentage. This will give you the mark up.

$23 * 92% = $21.16

Now to find the total selling price, we add the cost and the mark up together.

$23 + $21.16 = $44.16

Please help with this one :/
Naddika [18.5K]

Answer:

6.3°

Step-by-step explanation:

\because \: \pi^{c}  = 180 \degree \\  \\  \therefore \: 1^{c}  =  \frac{180 \degree }{\pi}  \\  \\  \therefore \: 0.11^{c}  =  \frac{180 \degree }{3.14}   \times 0.11 \\  \\ \therefore \: 0.11^{c}  =  \frac{180 \degree }{314}   \times 11 \\ \\  \therefore \: 0.11^{c}  =  \frac{1980 \degree }{314}   \times 11 \\ \\ \therefore \: 0.11^{c}  = 6.30573248\degree  \\  \\   \huge \red{ \boxed{\therefore \: 0.11^{c}  = 6.3\degree }} \\  \\
